W SCHRACK PRODUCT QUALITY
We offer our customers a well sorted product range offering the highest levels of product availability. Our aim is ultra-
efficiency when it comes to customerspecific solutions. This is possible thanks to standardized work processes, modularisation
and the use of software aids.
W SCHRACK ISO-CERTIFIZIED
In recent times, testing procedures for ISO certification have shifted their focus very strongly on how organisations deal with
customers, and the associated customer processes. Some of the major areas which are inspected include:
• General customer communication
• Dealing with offers and tenders in a structured manner
• Transparency in all areas of the company in direct or indirect contact with customers
• The above is required in all tiers of management
ISO certification is by no means the norm. Our ISO certification 9001:2000 is both a reward as well as an obligation. The
obligation we have in accepting this certification is to ensure the documentation of our work processes and to continuously
improve such processes.

W LSD CONTACTORS FOR SWITCHING MOTORS, 3-POLE, 3 ... 250 kW –GENERAL INFORMATIONS
AC AND DC OPERATIONIEC 60947, EN 60947 (VDE 0660). The LSD contactors are climate-proof. They are finger-safe according to EN 50274. Sizesize 00 contactors have an auxiliary contact integrated in the basic unit. The basic units of sizes 0 to 3 contain only the maincurrent paths. All basic units can be extended with auxiliary contacts and contact blocks.
CONNECTION METHODSThe LSD contactors are available with screw terminals (box terminals and connecting bars) or with Cage Clamp terminals.The size 3 contactors have removable box terminals for the main conductor connections. This permits connection of ring terminal lugs or busbars.
CONTACT RELIABILITYIf voltages ≤ 110 V and current ≤ 100 mA are to be switched, the auxiliary contacts of the LSD contactor or LSH auxiliarycontactor should be used as they guarantee a high level of contact reliability. These auxiliary contacts are suitable for solid-state circuits with currents ≥ 1 mA at a voltage of 17 V.
SHORT-CIRCUIT PROTECTION OF THE CONTACTORSShort-circuit protection of the contactors without overload relay, see Technical specifications. For short-circuit protection ofthe contactors with overload relay, see "Thermal Overload Relays". To assemble fuseless motor feeders you must select combinations of motor protection switches (MPS) and contactor.
MOTOR PROTECTIONLST thermal overload relays can be fitted to the LSD contactors for protection against overload. The overload relays must beordered separately.
RATINGS OF INDUCTION MOTORSThe quoted rating (in kW) refers to the output power on the motor shaft (according to the nameplate).
SURGE SUPPRESSIONLSD contactors can be retrofitted with RC elements, varistors, diodes or diode assemblies (assembly of diode and Zener diodefor short break times) for damping opening surges in the coil. The surge suppressors are plugged onto the front of size 00contactors. Space is provided for them next to a snap-on auxiliary contact block. For sizes 0 to 3 contactors, varistors andRC elements can be snapped on either on the top or directly below the coil terminals. Diode assemblies are available in 2 different versions on account of their polarity. Depending on the application they can be connected either only at the bottom (assembly with MPS) or only at the top (assembly with overload relay). The plug-in direction of the diodes and diodeassemblies is specified by coding.Exceptions:LSZD0006, in this case the plug-in direction is marked with "+" and "-"Auxiliary contactors are supplied either without surge suppression or with a varistor or diode connected as standard, according to the version.Note:The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are damped against voltage peaks (noise suppression diode 6 to 10 times; diode assemblies 2 to 6 times, varistor +2 to 5 ms).

The magnetic coil is switched directly on and off with the control supply voltage Us by way of terminals A1/A2.
MULTI-VOLTAGE RANGE FOR THE CONTROL SUPPLY VOLTAGE US:Several closely adjacent control supply voltages, available around the world, are covered by just one coil, for example 110-115-120-127 V UC or 220-230-240 V UC. In addition, allowance is also made for a coil operating range of 0.8 timesthe lower (Us min) and 1.1 times the upper (Us max) rated control supply voltage within which the contactor switchesreliably and no thermal overloading occurs.
W LSD CONTACTORS FOR SWITCHING MOTORS, 3-POLE, 3 ... 250 kW –GENERAL INFORMATIONS
• LSD contactors for switching motors• LSR contactors for AC-1 applications
UC OPERATIONThe contactors can be operated with AC (40 to 60 Hz) as well as with DC.
WITHDRAWABLE COILSFor simple coil replacement, e.g. if the application is replaced, the magnetic coil can be pulled out upwards after the releasemechanism has been actuated and can be replaced by any other coil of the same size.
AUXILIARY CONTACT COMPLEMENTThe contactors can be fitted with up to 8 auxiliary contacts (identical auxiliary contact blocks from sizes 0 to 12). Of these,no more than 4 are permitted to be NC contacts.

• The contactors are suitable for use in any climate
• They are finger-safe according to EN 50274
W TECHNICAL DATAThe LSK capacitor contactors are special version of the size 00-3 ALEA contactors. The capacitors are precharged by means ofthe mounted leading NO contacts and resistors; only then do the main contacts close. This prevents disturbances in the net-work and welding of the contactors. Only discharged capacitors are permitted to be switched on with capacitor contactors.The auxiliary contact block which is snapped onto the capacitor contactor contains the three leading NO contacts and in thecase of size 00 one standard NC contact and in the case of size 0 and size 3 one standard NO contact, which is unassigned.Size S00 also contains another unassigned NO contact in the basic unit. In addition, a 2-pole auxiliary contact block can bemounted laterally on the LSK3 capacitor contactors (1 NO + 1 NC versions) type LSZ0D711. The fitting of auxiliary contacts forLSKD and LSK0 is not expandable.

• ALEA controls are climate-proof and are suitable and tested for use worldwide.• If the devices are used in ambient conditions which deviate from common industrial conditions (EN60721-3-3 “Stationary
Use, Weather-Protected“), the manufacturer must be consulted about possible restrictions with regard to the reliability andendurance of the device and possible protective measures.
Endurance of the main contacts
The characteristic curves show the contact endurance of the contactors when switchingresistive and inductive AC loads (AC-1/AC-3) depending on the breaking current andrated operational voltage. It is assumed that the operating mechanisms are switchedrandomly, i.e. not synchronized with the phase angle of the supply system.The rated operational current Ie complies with utilization category AC-4 (breaking six timesthe rated operational current) and is intended for a contact endurance of at least 200 000operating cycles.If a shorter endurance is sufficient, the rated operational current Ie/AC-4 can be increased.If the contacts are used for mixed operation, i.e. normal switching (breaking the ratedoperational current according to utilization category AC-3) in combination with intermittentinching (breaking several times the rated operational current according to utilizationcategory AC-4), the contact endurance can be calculated approximately from the followingequation:
Characters in the equation:X Contact endurance for mixed operation in operating cyclesA Contact endurance for normal operation (Ia = Ie) in operating cyclesB Contact endurance for inching (Ia = multiple of Ie) in operating cyclesC Inching operations as a percentage of total switching operations

W LSDH VACUUM CONTACTORS, 3-POLE, 335 ... 450 kW – OVERVIEW
IEC 60947-4-1, EN 60947-4-1 (VDE 0660 Part 102)The LSDH contactors are climate-proof. They are finger-safe according to EN 50274. Terminal covers may have to be fitted onto the connecting bars, depending on the configuration with other devices (see chapter “Products and ordernumbers” – terminal covers).
W FUNCTION
W MAIN CONTACTSContact erosion indication with LSDH 6/8 vacuum contactorsThe contact erosion of the vacuum interrupters can be checked during operation with the help of 3 white double slideson the contactor base. If the distance indicated by one of the double slides is < 0.5 mm while the contactor is in the closedposition, the vacuum interrupter must be replaced. To ensure maximum reliability, it is recommended to replace all 3 vacuum interrupters.
W AUXILIARY CONTACTSContact reliabilityThe auxiliary contacts are suitable for solid-state circuits• With currents ≥ 1 mA• And voltages from 17 V.
W SURGE SUPPRESSIONControl circuitProtection of coils against overvoltages:
AC operation• Fitted with varistors as standard
DC operationRetrofitting options:• With varistorsIf LSDH 6/8 is to be used for DC operation, an additional reversing contactor is required; this is included in the scope ofsupply in the same packaging as the vacuum contactor.
W ELECTROMAGNETIC COMPATIBILITY (EMC)LSDH 6/8 contactors for AC operation are fitted with an electronically controlled solenoid operating mechanism with ahigh interference immunity.

Note:During operation in installations in which the emitted interference limits cannot be observed, e.g. when used for outputcontactors in converters, LSDH6/8 contactors without a main conductor path circuit are recommended (see descriptionnext page).
TECHNICAL SPECIFICATIONS
Page

W APPLICATIONThe standard LSDH6. and LSDHB. contactors with electronically controlled contactor mechanism, have high resistance toelectromagnetic interference.
Causes for such interference can be, for example:• Frequency converters which are operated nearby can cause periodic overvoltages at the control level of the contactors.• High-energy pulses cause by switching operations and atmospheric discharges can cause interference on the control
cables.
To reduce interference voltages caused by frequency converters, the manufacturer recommends the use of e.g. input filters, output filters, grounding or shielding in the installation.
Further measures that should be applied for overvoltage damping:• Feeding the contactors using control transformer according to EN 60204 - rather than directly from the network• Use of surge arresters, if required
W CONNECTIONControl circuitThe rectifier bridge is connected to varistors for protection against overvoltages. The built-in rectifier bridge affords sufficient protection for the coils.Main circuitAs standard LSDH. contactors with integrated RC varistors.
W PROTECTION OF THE MAIN CURRENT PATHSAn integrated RC varistor connection for the main current paths of the contactors dampens the switching overvoltagerises to safe values. This prevents multiple restriking. The operator of an installation can therefore rest assured that themotor winding cannot be damaged by switching overvoltages with steep voltage rises.
Important note: The overvoltage damping circuit is not required if LSDH 6/8 contactors are used in circuits with DC choppers, frequencyconverters or speed-variable operating mechanisms, for example. It could be damaged by the voltage peaks andharmonics which are generated. This may cause phase-to-phase short-circuits in the contactors.
Solution: Order special contactor version without overvoltage damping. (on request)

Endurance of the auxiliary contacts
The contact endurance for utilization category AC-12 or AC-15/AC-14 depends mainly onthe breaking current. It is assumed that the operating mechanisms are switched randomly,i.e. not synchronized with the phase angle of the supply system.

W ACCESSORIES FOR LSD AND LSH AUXILIARY CONTACTORS – OVERVIEW
W SNAP-ON AUXILIARY CONTACT BLOCKSThe auxiliary contact blocks and the maximum number of contacts that can be mounted are described in the sections„Contactors“ and „Auxiliary Contactors“.
OperationIn the case of the versions for rated control supply voltages of 110 V and 230 V, either AC voltage or DC voltage can be appliedon the line side, whereas the variant for 24 V is designed for DC operation only. A DC-operated contactor is connected to theoutput in accordance with the input voltage that is applied. The mean value of the OFF-delay is approximately 1.5 times thespecified minimum time.
W SURGE SUPPRESSION• (also for Cage Clamp terminals on request) size 00, 0, 2, 3, 6 to 12All LSD contactors and LSH auxiliary contactors can be retrofitted with RC elements or varistors for damping opening surgesin the coil. Diodes or diode assemblies can be used. The surge suppressors are plugged onto the front of size 00 contactors.Space is provided for them next to a snap-on auxiliary contact block. With all size 0 to 3 contactors, varistors, RC elements anddiode assemblies can be plugged on directly at the coil terminals, either on the top or underneath. The plug-in direction of thediodes and diode assemblies is determined by a coding device. Auxiliary contactors are supplied either without overvoltagedamping or with a varistor or diode connected as standard, according to the version.
Note: The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils aredamped against voltage peaks (noise suppression diode 6 to 10 times; diode assemblies 2 to 6 times, varistor +2 to 5 ms).
W SOLDER PIN ADAPTERSThe solder pin adapters for the size 00 contactors are available in version for:• contactors with one integrated auxiliary contact
W SEALABLE COVERS FOR SIZES 00 TO 12 (ON REQUEST)When contactors and auxiliary contactors are used in safety-oriented applications, it must be ensured that it is impossible to operate the contactors manually. For ALEA contactors there are sealable covers available for this purpose on requets; these preventaccidental manual operation. These are transparent molded-plastic caps with a bracket that enables the contactor to be sealed.

W LSK CAPACITOR SWITCHING CONTACTORS – OVERVIEW
W AC OPERATIONIEC 60947, EN 60947 (VDE 0660)The contactors are suitable for use in any climate. They are finger-safe according to EN 50274. The LSK capacitor contactorsare special version of the size 00 to 3 ALEA contactors. The capacitors are precharged by means of the mounted leading NOcontacts and resistors; only then do the main contacts close. This prevents disturbances in the network and welding of thecontactors. Only discharged capacitors are permitted to be switched on with capacitor contactors. The auxiliary contact blockwhich is snapped onto the capacitor contactor contains the three leading NO contacts and in the case of 00 one standard NCcontact and in the case of 0 and 3 one standard NO contact, which is unassigned. Size 00 also contains another unassignedNO contact in the basic unit. In addition, a 2-pole auxiliary contact block can be mounted laterally on the LSK3 capacitor contactors (1 NO + 1 NC versions); type LSZ0D711. The fitting of auxiliary switches for LSKD and LSK0 is not expandable. Forthe capacitor switching capacity of the basic LSD contactor version, see Technical specifications.

W LSW REVERSING CONTACTOR ASSEMBLIES – FUNCTION
The operating times of the individual LSD contactors are rated in such a way that no overlapping of the contact makingand the arcing time between two contactors can occur on reversing, providing they are interlocked by way of their auxiliary switches (NC contact interlock) and the mechanical interlock. For assemblies with AC operation and 50/60 Hz, adead interval of 50 ms must be provided when used with voltages ≥ 500 V. This dead times does not apply to assemblieswith DC operation. The operating times of the individual contactors are not affected by the mechanical interlock.
The following points should be noted:
Size 00• For maintained-contact operation:
Use contactors with an NC contact in the basic unit for the electrical interlock.• For momentary-contact operation:
Use contactors with an NC contact in the basic unit for the electrical interlock; in addition, an auxiliary contact block withat least one NO contact for latching is required per contactor.
Sizes 0 to 3• For maintained-contact operation:
The contactors have no auxiliary contact in the basic unit; NC contacts for the electrical interlock are therefore integratedin the mechanical interlock that can be mounted on the side of contactor (one contact each for the left and right-handcontactors).
• For momentary-contact operation:Electrical interlock as for maintained-contact operation; for the purpose of latching an auxiliary contact with an NO contact is additionally required for each contactor. This contact can be snapped onto the top of the contactors. Alternatively, auxiliary contact blocks mounted on the side can be used; they must be fitted onto the outside of each contactor.
W SURGE SUPPRESSIONSizes 00 to 3All contactor assemblies can be fitted with RC elements or varistors for damping opening surges in the coil.As with the individual contactors, the surge suppressors can either be plugged onto the top of the contactors (size 00) or fitted onto the coil terminals on the top or bottom (size 0 to 3).
W TECHNICAL SPECIFICATIONS
The technical specifications are identical to those of the LSD .. contactors.The CSA and UL approvals only apply to the complete contactor assemblies and not to the individual parts for customerassembly.

These LSY contactor assemblies for wye-delta starting are designed for standard applications.
Note:Contactor assemblies for wye-delta starting in special applications such as very heavy starting or wye-delta starting of special motors must be customized. Help with designing such special applications is available.
W COMPLETE UNITS UP TO SIZE 3The LSY contactor assemblies for wye-delta starting can be ordered as follows:Sizes 00 to 3:• Fully wired and tested, with electrical interlock, dead interval of up to 10 s on reversing (size 00 with electrical and
mechanical interlocks)
A dead interval of 50 ms on reversing is already integrated in the time relay function. There is also a range of accessories(auxiliary contact blocks, surge suppressors, etc.) that must be ordered separately.
For overload relays for motor protection, see "Thermal Overload Relays”
The LSY contactor assemblies have screw terminals and are suitable for screwing or snapping onto 35 mm standard mountingrails. Fully wired and tested LSY contactor assemblies have one unassigned NO contact which is mounted onto the front of theK3 delta contactor.

W MOTOR PROTECTIONThermal overload relays can be used for overload protection. The overload relay can be either mounted onto the line contactor or separately fitted. It must be set to 0.58 times the rated motor current.
W FUNCTION
Wye-delta starting can only be used either if the motor normally operates in a Δ connection or starts softly or if the loadtorque during Y starting is low and does not increase sharply. On the Y step the motors can carry approximately 50 % (classKL 16) or 30 % (class KL 10) of their rated torque; The tightening torque is approximately 1/3 of that during direct on-linestarting. The starting current is approximately 2 to 2.7 times the rated motor current.
The changeover from Y to Δ must not be effected until the motor has run up to rated speed. Operating mechanisms whichrequire this changeover to be performed earlier are unsuitable for wyedelta starting.
The ratings given in the table are only applicable to motors with a starting current ratio IA ≤ 8.4 x IN and using wye-deltatiming relay with a dead interval on reversing of approximately 50 ms.
W SURGE SUPPRESSIONSizes 00 to 3:All contactor assemblies can be fitted with RC elements, varistors or diode assemblies for damping opening surges in thecoil. As with the individual contactors, the surge suppressors can either be plugged onto the top of the contactors (size 00)or fitted onto the coil terminals on the top or bottom (size 0 to 3).

THERMAL OVERLOAD RELAYS
W LST THERMAL OVERLOAD RELAYS – GENERAL INFORMATIONS
W SCHRACK INFOThe LST thermal overload relays up to 100 A have been designed for inverse-time delayed protection of loads with normal starting against excessive temperature rises due to overload or phase failure. An overload or phase failure resultsin an increase of the motor current beyond the set rated motor current. Via heating elements, this current rise heats upthe bimetal strips inside the device which then bend and as a result trigger the auxiliary contacts by means of a trippingmechanism. The auxiliary contacts then switch off the load by means of a contactor. The break time depends on the ratiobetween the tripping current and set current Ie and is stored in the form of a long-term stable tripping characteristic. The"tripped" status is signaled by means of a switch position indicator. Resetting takes place either manually or auto maticallyafter the recovery time has elapsed. The devices are manufactured in accordance with environmental guidelines and contain environmentally friendly and reusable materials.
W DESIGN AND FUNCTION
W DEVICE CONCEPTThe LST thermal overload relays are compact devices, i.e. current measurement and the evaluation unit are integrated in a single enclosure.
W MOUNTING OPTIONSThe LST thermal overload relays can be mounted directly onto the LSS/LSD contactors (exception: size 00 with Cage Clampconnection can only be installed as a stand-alone installation). The devices can also be installed as stand-alone installations with the corresponding terminal brackets.
W CONNECTION METHODAll sizes of the LST thermal overload relays with screw terminal can be connected to the auxiliary and main current paths.Rails can be connected to the main conductor connections of size 3 overload relays if the box terminals are removed.As an alternative, the devices are also available with Cage Clamp terminals. The auxiliary conductor connections of thesedevices, and for size 00 the main conductor connections as well, are fitted with Cage Clamp terminals (on request).
W OVERLOAD RELAYS IN CONTACTOR ASSEMBLIES FOR WYE-DELTA STARTINGWhen overload relays are used in combination with contactor assemblies for wye-delta starting it must be noted that only 0.58 times the motor current flows through the line contactor. An overload relay mounted onto the line contactor must be set to 0.58 times the motor current. An assignment of the LST thermal overload relays to the line contactors of our LSY contactor assemblies for wye-delta starting can be found under "Power and Auxiliary Contactors".
W OPERATION WITH FREQUENCY CONVERTERThe LST thermal overload relays are suitable for operation with frequency converters. Depending on the frequency of theconverter, a higher current than the motor current must be used in some cases due to eddy-currents and skin effects.
(1) Connection for mounting onto contactors: Optimally adapted in electrical, mechanical and design terms to thecontactors and soft starters, these connecting pins can be used for direct mounting of the overload relays. Stand-alone installation is possible as an alternative (in some cases in conjunction with a stand-alone installation module).
(2) Selector switch for manual/automatic RESET and RESET button: With this switch you can choose between manual and automatic RESET. A device set to manual RESET can be reset locally by pressing the RESET button. A remote RESET is possible using the RESET modules (accessories), which are independent of size (on request).
(3) Switch position indicator and TEST function of the wiring: Indicates a trip and enables the wiring test.(4) Motor current setting: Setting the device to the rated motor current is easy with the large rotary knob.(5) STOP button: If the STOP button is pressed, the NC contact is opened. This switches off the contactor downstream.
The NC contact is closed again when the button is released.(6) Transparent, sealable cover Secures the motor current setting, TEST function and the selector switch for manual/
automatic RESET against adjustment.(7) Supply terminals: The generously sized terminals permit connection of two conductors with different cross-sections
for the main and auxiliary circuits. The auxiliary circuit can be connected with screw terminals and alternatively with spring-loaded terminals (on request).

THERMAL OVERLOAD RELAYS
W BASIC FUNCTIONSThe LST thermal overload relays are designed for:• Inverse-time delayed protection of loads from overloading• Inverse-time delayed protection of loads from phase failure
W CONTROL CIRCUITThe LST thermal overload relays do not require an additional supply voltage for operation.
W SHORT-CIRCUIT PROTECTIONFuses or motor starter protectors must be used for short-circuit protection.
W TRIP CLASSESThe LST thermal overload relays are available for normal starting conditions with trip class 10.
W PHASE FAILURE PROTECTIONThe LST thermal overload relays are fitted with phase failure sensitivity in order to minimize temperature rises of the load in the case of a phase failure during single-phase operation.
W SETTINGThe LST thermal overload relays are set to the rated motor current by means of a rotary knob. The scale of the rotary knob is shown in ampere.
W MANUAL AND AUTOMATIC RESETAutomatic and manual reset is selected by pressing and turning the blue button (RESET button). If the button is set to manual reset, the overload relay can be reset directly by pressing the RESET button. Resetting is possible in combinationwith mechanical and electrical reset options from the range of accessories. If the blue button is set to automatic RESET,the relay is reset automatically. The time between tripping and resetting is determined by the recovery time.
W RECOVERY TIMEAfter tripping due to overload, the LST thermal overload relays require some time until the bimetal strips have cooled down. The device can only be reset after the bimetal strips have cooled down. This time (recovery time) depends on the tripping characteristics and strength of the tripping current. The recovery time allows the load to cool down after tripping due to overload.
W TEST FUNCTIONThe TEST slide can be used to check whether the operational LST thermal overload relay is working properly. Actuating the slide simulates tripping of the relay. During this simulation the NC contact (95-96) is opened and the NO contact (97-98) is closed. This tests whether the auxiliary circuit has been correctly connected to the overload relay. If the LSTthermal overload relay has been set to automatic RESET, the overload relay is automatically reset when the TEST slide isreleased. The relay must be reset with the RESET button if it has been set to manual RESET.
W STOP FUNCTIONIf the STOP button is pressed, the NC contact is opened. This switches off the contactor downstream and thus the load. The load is switched on again when the STOP button is released.
W DISPLAY OF THE OPERATING STATEThe respective operating state of the LST thermal overload relay is displayed by means of the position of the marking on the TEST function/switch position indicator slide. After tripping due to overload or phase failure, the marking on the slideis to left on the "O" mark, otherwise it is on the "I" mark.
W AUXILIARY CONTACTSThe LST thermal overload relays are fitted with an NO contact for the "tripped" signal, and an NC contact for disconnecting the contactor.

W THERMAL OVERLOAD RELAYS – CHARACTERISTIC CURVES
W SCHEMATIC REPRESENTATION OF A CHARACTERISTIC CURVE
The tripping characteristics show the relationship between the tripping time and tripping current as multiples of the setcurrent Ie and are given for symmetrical three-pole and two-pole loads from the cold state. The smallest current used fortripping is called the minimum tripping current. According to IEC 60947-4-1, this current must be within specified limits.The limits of the minimum tripping current for the LST thermal overload relays for symmetrical three-pole loads are between 105 % and 120 % of the set current. The tripping characteristic starts with the minimum tripping current andcontinues with higher tripping currents based on the characteristics of the so-called trip classes (CLASS 10, CLASS 20etc.). The trip classes describe time intervals within which the overload relays have to trip with 7.2 times the set currentIe from the cold state for symmetrical three-pole loads.
The tripping characteristic for a three-pole LST thermal overload relay (see characteristic curve for symmetrical three-poleloads from the cold state) only applies if all three bimetal strips are simultaneously loaded with the same current. If onlytwo bimetal strips are heated due to a phase failure, these two strips alone must generate the necessary force to triggerthe tripping mechanism which would result in a longer tripping time or require a higher current. If these higher currentsare applied over a longer period, they usually cause damage to the load. To avoid damage, the LST thermal overloadrelays are fitted with phase failure sensitivity which ensures faster tripping in accordance with the characteristic curve fordouble-pole loads from the cold state by means of a suitable mechanical mechanism. Compared with a cold load, a loadat operating temperature obviously has a lower temperature reserve. This is taken into account by the LST thermal over-load relays by reducing the tripping time to about 25 % when loaded with the set current Ie for an extended period.
The tripping times are as follows for:
The characteristic curves for the individual LST thermal overload relays can be requested from Technical Assistance.

An auxiliary switch block can be inserted transversely on the front. The overall width of the motor protection switches remains unchanged.
One of the two auxiliary switches can be mounted laterally for each motor protectionswitches The contacts of the auxiliary switch close and open together with the maincontacts of the motor protection switches. The overall width of the lateral auxiliary switch with 2 contacts is 9 mm.
One signaling switch can be mounted at the side of each motor protection switcheswith a rotary operating mechanism. The signaling switch has two contact systems.One contact system always signals tripping irrespective of whether this was causedby a short-circuit, an overload or an auxiliary trip unit. The other contact system only switches in the event of a short-circuit. There is no signaling as a result of switchingoff with the handle. In order to be able to switch on the motor protection switchesagain after a short-circuit, the signaling switch must be reset manually after the errorcause has been eliminated. The overall width of the signaling switch is 18 mm.
For remote-controlled tripping of the motor protection switches. The release coilshould only be energized for short periods (see schematics).
Trips the motor protection switches when the voltage is interrupted and prevents themotor from being restarted accidentally when the voltage is restored. Used for remote-controlled tripping of the motor protection switches. Particularly suitable forEMERGENCY-STOP disconnection by way of the corresponding EMERGENCY-STOPpushbutton according to DIN VDE 0113.
W ROTARY OPERATING MECHANISMS (DOOR-COUPLING) SIZE 0 TO 3
W SCHRACK INFOMotor protection switches with a rotary operating mechanism can be mounted in a controlcabinet and operated externally by means of a door-coupling rotary operating mechanism.When the cabinet door with motor protection switches is closed, the operating mechanismis coupled. When the motor protection switches closes, the coupling is locked which prevents the door from being opened unintentionally. This interlock can be defeated by themaintenance personnel. In the open position, the rotary operating mechanism can be secured against reclosing with up to 3 padlocks. Inadvertent opening of the door is not possible in this case either.

W BES – GENERAL INFORMATIONS
W SCHRACK INFOBES motor protection switches are compact, current limiting motor protection switches which areoptimized for load feeders. The motor protection switches are used for switching and protectinginduction motors of up to 45 kW at 400 V AC and for other loads with rated currents of up to 100A.
W TYPE OF CONSTRUCTIONThe motor protection switches are available in four sizes:• Size 00 – width 45 mm, max. rated current 12 A, at 400 V AC suitable for induction motors up to 5.5 kW.• Size 0 – width 45 mm, max. rated current 25 A, at 400 V AC suitable for induction motors up to 11 kW.• Size 2 – width 55 mm, max. rated current 50 A, at 400 V AC suitable for induction motors up to 22 kW.• Size 3 – width 70 mm, max. rated current 100 A, at 400 V AC suitable for induction motors up to 45 kW.
W NOTETechnical specifications by green backgrounds. The devices with Cage Clamp terminals are on request.
W SCREW TERMINALSBES motor protection switches of sizes 00 and 0 are fitted with terminals with captive screws and clamping pieces, allowingthe connection of 2 conductors with different cross-sections. The box terminals of the size 2 and 3 motor protection switchesalso enable 2 conductors with different cross-sections to be connected. With the exception of size 3 motor protection switcheswhich are equipped with 4 mm Allen screws, all terminal screws are tightened with a Pozidriv screwdriver size 2. The box terminals of the size 3 motor protection switches can be removed in order to connect conductors with cable lugs or connectingbars. A terminal cover is available as touch protection and to ensure that the required clearances and creepage distances are maintained if the box terminals are removed.
W BES MOTOR PROTECTION SWITCHES SIZE 00 WITH CAGE CLAMP TERMINALS (ON REQUEST)
W SCHRACK INFOAs an alternative to screw terminals, size 00 motor protection switches are also available with Cage Clamp terminals. Thisscrewless connection method, already familiar from terminal blocks, clamps the conductors using a spring-loaded terminal andis shock-proof and vibration-proof. Motor protection switches with Cage Clamp terminals allow independent connection of twoconductors per terminal.
W MOUNTINGThe motor protection switches are snap-fitted an a 35 mm standard mounting rail to EN 60715. A standard mounting rail witha height of 15 mm is required for size S3 motor protection switches. A 75 mm standard mounting rail can be used as an alternative for size 3.

W INSTALLATION GUIDELINES, FUNCTION AND CONFIGURATION
W TRIP UNITSBES motor protection switches are equipped with inverse-time delayed overload release based on the bimetal principle and with instantaneous electronic trip units (electromagnetic shortcircuit releases). The overload releases can be adjusted in accordance with the load current. The electronic trip units are permanently set to a value 13 times the rated current and thus enable trouble-free starting of motors. The scale cover can be sealed to prevent unauthorized adjustments to the set current.
W TRIP CLASSESThe trip classes of thermally delayed trip units are based on the tripping time (tA) at 7.2 times the set current in cold state (excerpt from IEC 60947-4):• CLASS 10: 4 s < tA < 10 sThe motor protection switches must trip within this time!
W OPERATING MECHANISMSSize 00 motor protection switches are actuated by a rocker operating mechanism and size 0, 2 and 3 motor protection switches by a rotary operating mechanism. If the motor protection switches trips, the rotary operating mechanism switches to the tripped position to indicate this. Before the motor protection switches is reclosed, the rotary operating mechanism must be reset manually to the 0 position. Only then can the motor protection switches be set again to the I position. In the case of motor protection switches with rotary operating mechanisms, an electrical signal can be output by a signaling switch to indicate that the motor starter protector has tripped. All operating mechanisms can be locked in the 0 position with a padlock (shackle diameter 3.5 mm to 4.5 mm). The motor protection switches isolating function complies with IEC 60947-2.
W PREVENTION OF UNINTENDED TRIPPINGIn order to prevent premature tripping due to the integrated phase failure sensitivity, motor protection switches should alwaysbe connected to ensure current flows through all three main current paths.
W SHORT-CIRCUIT PROTECTIONIf a short-circuit occurs, the short-circuit releases of BES motor protection switches isolate the faulty load feeder from the network and thus prevent further damage. Motor protection switches with a short-circuit breaking capacity of 50 kA or 100 kA are virtually short-circuit resistant at a voltage of 400 V AC, since higher short-circuit currents are not to be expected in practice.
W MOTOR PROTECTIONThe tripping characteristics of BES motor protection switches are designed mainly to protect induction motors. The motor protec-tion switches are therefore also referred to as motor circuit breakers. The rated current In of the motor to be protected is set on the setting scale. Factory setting of the short-circuit release is 13 times the rated current of the motor protection switches. This permits trouble-free starting and ensures that the motor is properly protected. The phase failure sensitivity of the motor protection switches ensures that it is tripped in time in the event of a phase failure and overcurrents that occur as a result in the other phases. Motor protection switches with thermal overload releases are normally designed in accordance with trip class 10.
MOTOR PROTECTION SWITCHES UP TO 100A
Page
175
W SYSTEM PROTECTIONThe BES motor protection switches for motor protection are also suitable for plant protection. In order to prevent premature tripping due to phase failure sensitivity, the three conducting paths must always be uniformly loaded. The conducting paths must be connected in series the case of single-phase loads.
W SHORT-CIRCUIT PROTECTION FOR STARTER COMBINATIONSThe BES motor protection switches for starter combinations in sizes 0, 2 and 3 provide short-circuit protection with the help of a contactor and overload relay combination. Like the motor protection switches for motor protection, they are equipped with short-circuit releases which are permanently set to a value equivalent to 13 times the rated current of the motorprotection switches. They are not equipped with overload releases. On overload, the overload relay triggers the contactor, the motor protection switches remains closed. Only when a short-circuit occurs in the feeder does the motor protection switches trip as well. The motor protection switches for starter combinations must always be used in combination with an overload relay because the motor protection switches alone cannot protect the motor and itself against overload.
W MAIN AND EMERGENCY-STOP SWITCHESThe BES motor protection switches comply with the isolating function to IEC 60947-2, therefore they can be used – taking IEC60204-1 into account – as main and EMERGENCY-STOP switches. BES door-coupling rotary operating mechanisms for heavy duty also comply with the requirements for the isolating function.
W USE OF IT SYSTEMS (IT NETWORKS)BES motor protection switches are suitable for operation in IT systems according to IEC 60947-2. In the event of a 3-pole short-circuit, their response in this system is the same as in others: Therefore, the same short-circuit breaking capacity Icu andIcs applies, see "Technical specifications". An initial fault (ground fault) does not necessarily force immediate disconnection of the network when operating IT systems. If a second independent error occurs (ground fault), the switching capacity of the motor protection switches might be reduced. This is the case if both ground faults occur in different phases and if one of the ground faults occurs on the input side and the other on the outgoing terminal of the motor protection switches. In order to maintain the short-circuit function of the motor protection switches even with two independent ground faults (doubleground faults), the reduced short-circuit breaking capacity with double ground faults must be taken into account in IT systemsIcuIT (see "Technical specifications"). If a ground fault is instantaneously recognized and remedied (ground-fault monitoring), the risk of double ground fault and thus reduced short-circuit breaking capacity IcuIT can be minimized.
W SWITCHING OF DC CURRENTSBES motor protection switches for alternating currents are also suitable for DC switching. The maximum permissible DC voltage per conducting path must, however, be adhered to. Higher voltages require a series connection with 2 or 3 conducting paths. The response values of the overload release remain unchanged; the response values of a short-circuit release increase by approximately 30 % for DC. The example circuits for DC switching can be seen in the table below.

Notes
150 V DC 2-pole switching, non-grounded system1)
If there is no possibility of a ground fault, or if every ground fault is rectified immediately (ground-fault monitoring), then the maximum permitted DC voltage can be tripled.
300 V DC 2-pole switching, grounded system
The grounded pole is always assigned to the individual conducting path, so that there are always 2 conducting paths in series in the event of a ground fault.

3 conducting paths in series. The grounded pole is assigned to the unconnectedconducting path.

Short-circuit breaking capacity IcuIT in the IT system (IT network) according to IEC60947-2BES motor protection switches are suitable for operation in IT systems. Values valid for triple-pole short-circuit are Icu up to Ics.In case of double ground fault on different phases at the input and output side of a motor protection switches, the specialshort-circuit breaking capacity IcuIT applies. The specifications in the table below apply to BES motor protection switches. In the colored areas, IcuIT is 100 kA, or in some ranges it is 50 kA. Therefore the motor protection switches are short-circuit resistant in these ranges.If the short-circuit current at the place of installation exceeds the rated short-circuit breaking capacity of the motor protectionswitches as specified in the table, a back-up fuse is required. The maximum rated current for the back-up fuse is specified inthe tables. The rated short-circuit breaking capacity then applies as specified on the fuse.

CHARACTERISTIC CURVES
W BES MOTOR PROTECTION SWITCHES – CHARACTERISTIC CURVES
W REPRESENTATION OF TYPICAL TIME/CURRENT CHARACTERISTIC OF BES
The time/current characteristic, the current limiting characteristics and the I2t characteristic curves were determinedaccording to DIN VDE 0660 and IEC 60947. The tripping characteristic of the inverse-time delayed overload release (thermal overload releases, 'a' releases) for DC and AC with a frequency of 0 Hz to 400 Hz applies for the time/currentcharacteristic. The characteristic curves apply to the cold state; at operating temperature, the tripping times of the thermal trip unitsare reduced to approximately 25 %. Under normal operating conditions, all three poles of the device must be loaded.The three main current paths must be connected in series in order to protect single-phase or DC loads.With 2-pole and 3-pole loading, the maximum deviation in the tripping time of 3 times the set current and upwards is±20 % and thus in accordance with DIN VDE 0165. The tripping characteristics for the instantaneous, electromagneticelectronic trip units (short-circuit releases, 'n' releases) are based on the rated current In that also represents the maximum value of the setting range for motor protection switches with adjustable overload releases. If the current is setto a lower value, the tripping current of the 'n' release is increased by a corresponding factor. The characteristic curves of the electromagnetic electronic trip units apply to frequencies of 50 Hz/60 Hz. Appropriatecorrection factors must be used for lower frequencies down to 16 2/3 Hz, for higher frequencies up to 400 Hz and forDC.
The above characteristic curve for the motor starter protector relates to a specific setting range. It is, however,also valid as a schematic representation of motor protectionswitches with other current ranges. Time/current characteristic curves, current limiting characteristic curvesand I2t curves are available.

200
1. Scope 1.1 These General Terms shall govern legal transactions between business en-

Software transactions are with precedence governed by the Software Conditions issued by the Austrian Electrical and Electron-ics Industry Association, assembly work by the Terms and Conditions for Assembly Work issued by the Austrian Power Current and Light Current Engineering Industry and/or (where applicable) the Terms and Conditions for the Assembly of Electrical Equipment used in Medicine issued by the Austrian Electrical and Electronics Industry (the current versions are avail-able at www.feei.at).
1.2 Any departure from the terms and conditions mentioned in 1.1 above shall be valid only if expressly accepted in writing by Seller.
2. Submission of offers 2.1 Seller’s offers shall be deemed offers without engagement. 2.2 Tender documents and project documentation must not be duplicated nor
made available to third parties without the permission of Seller. They may be claimed back at any time and shall be returned to Seller immediately if the order is placed elsewhere.
3. Conclusion of contract
of an order received or upon dispatch of a delivery. 3.2 Particulars appearing in catalog, folders etc. as well as any oral or written
statements shall only be binding if Seller makes express reference to them
3.3 Subsequent amendments of or additions to the contract shalI be subject to

ing and packaging, loading, disassembly, take-back and proper recycling and disposal of waste electrical and electronic equipment for commercial
Electrical Equipment. Buyer shall be liable for any and all charges, taxes or other duties levied in respect of delivery. If the terms of delivery include transport to a destination designated by Buyer, transport costs as weIl as the cost of any transport insurance desired by Buyer shall be borne by the latter. Delivery does not, however, include unloading and subsequent handling. Packaging materials will be taken back only by express agreement.
4.2 Seller reserves the right to modify prices if the order placed is not in accord-ance with the offer submitted.
event that the costs have increased by the time of delivery, Seller shall have the right to adjust prices accordingly.
4.4 In carrying out repair orders, Seller shall provide all services deemed ex-pedient and shall charge Buyer for the same on the basis of the work input and/or expenditures required. The same holds for any services or additional services the expediency of which becomes apparent only as the repair order
-quired.
4.5 Expenses for estimates of costs of repair and maintenance or for expert valuations shall be invoiced to Buyer.
5. Delivery 5.1 The period allowed for delivery shall commence at the latest of the follow-
ing dates:
-
c) the date of receipt by Seller of a deposit or security due before delivery of the goods in question.
5.2 Buyer shall obtain whatever licences or approvals may be required from authorities or third parties for the construction of plant and equipment. If the granting of such licences or approvals is delayed for any reason the delivery period shall be extended accordingly.
5.3 Seller may carry out, and charge Buyer for, partial or advance deliveries. If delivery on call is agreed upon, the commodity shall be deemed called off at the Iatest one year after the order was placed.
5.4 In case of unforeseeable circumstances or circumstances beyond the parties control, such as all cases of force majeure, which impede compliance with the agreed period of delivery, the latter shall be extended in any case for the
-ance, damages in transit, energy shortage and raw materials scarcity, labor disputes, and default on performance by a major component supplier who is
irrespective of whether they affect Seller or his subcontractor(s). 5.5 If a contractual penalty for default of delivery was agreed upon by contract-
ing parties when the contract was concluded, it shall be executed as follows, and any deviations concerning individual items shall not affect the remain-ing provisions: Where delay in performance can be shown to have occurred solely through the fault of Seller, Buyer may claim for each completed week of delay an indemnity of at most one half of one per cent, a total of no more than 5 %, however, of the value of that part of the goods to be delivered which cannot be used on account of Seller’s failure to deliver an essential part thereof, provided the Buyer has suffered a damage to the aforesaid extent. Assertion of rights of damages exceeding this extent is precluded.
6. Passage of risk and Place of performance 6.1 Enjoyment and risk shall pass to Buyer at the time of departure of the goods ex
works or ex warehouse regardless of the terms of quotation (such as carriage paid, C.I.F. etc.) agreed upon. This provision also includes the case of shipment being effected, organised and supervised by Seller and the case of delivery be-ing made in connection with assembly work to be undertaken by Seller.
