Introduction

A protection device like the Record PlusTM circuitbreaker is used in a wide variety of environments toprotect conductors, equipment and devices in lowvoltage distribution circuits. To use this product to itsfull potential it is necessary to verify that it functionscorrectly in the environment in which it is used andthat it meets the Electrotechnical requirements of thecircuit it protects.

EnvironmentRecord PlusTM breakers function well in almost anyindustrial environment . The EN 60947-2 defines themain aspects of what is meant by "industrialenvironment":Temperature:Relative humidity:Altitude:Pollution:Network harmonic content:Shock and vibration resistance:

For conditions other than the above mentioned pleaserefer to page D.16 in which the effects of theenvironment are defined.

Maximum short-circuit currentProtective devices as the Record PlusTM circuit breakermust be able to interrupt the maximum short-circuitcurrent at the point where they are installed. The interruption ratings of these breakers (breakingcapacity) can be found elsewhere in this catalog.

Design current of a circuitThe equipment and devices in an electrical circuitdetermines it's current load. The electrical conductorcross sections that can be used in the circuit aredetermined by a number of factors i.e.

- The design current of the circuit (IB).- Conductor type and it's insulation.

(current capacity = IZ)- Installation method.- Temperature.- Number of conductors mounted in each others

vicinity.

The resulting combinations of current load andelectrical conductor cross sections are beyond thescope of this catalogue, however a number offrequently used values are:

The breaker settingsThe main breaker settings are :- Overload protection or LT setting ... Ir- Magnetic or ST setting …. Im

Ir settingThe HD 384 (IEC 364) installation regulations state thatthe Ir value is determined by use of the following twoformulae:

IB < Ir ≤ IZIt ≤ 1.45 x IZ

TerminologyIB = Circuit design currentIr = Current set on breakerIZ = Current carrying capacity of electrical conductorIt = Tripping current of the protection device(Record PlusTM MCCB It ≤ 1.3 x Ir)

Use of the above mentioned formulae and the Record PlusTM characteristics give the following results: Breaker setting Ir ≤ IZ (It ≤ 1.3 x IZ)In practice Ir is generally set at a value equal to IZ.

Im setting - protected equipmentThe magnetic or ST setting of a breaker (Im) is primarilydefined by the characteristics of the equipment anddevices in the circuit . The Record PlusTM device is equipped with trip unitsthat react to fault currents when needed but arespecifically designed not to react to most inrush-current profiles. The details included in this section on devices as LV/LVtransformers and the time current curves of thebreaker published elsewhere in this catalogue allow adefinition of the Im value.

Im setting - protected linesOn a short-circuit event the total circuit impedancedetermines the highest and the lowest current that canflow in the circuit . It is necessary not only to verify ifthe protective device can interrupt the maximum short-circuit value but also if the device protecting thecircuit reacts and disconnects in time at the lowestpossible short-circuit value.Due to the fact that a major part of the circuitimpedance is formed by electrical conductors likecables, busbar systems etc. within the circuit , thisrequirement has a limiting effect on the length of theconductors used in the circuit .

There are two conditions that have to be met: a) The weakest short-circuit current must be

disconnected before the electrical conductorsexceed their temperature limits.

b) A current to earth (fault current) must bedisconnected before inadvertent contact tonormally non-conductive parts causes injury.

Please refer to the pages E.6 and E.13 for more details.

Protection against short-circuits

Weakest short-circuit current

It is necessary to verify that the permissible thermalstress in conductors is not exceeded at the maximumshort-circuit level and at the weakest short-circuit level.Verification on the maximum short-circuit level isdescribed on page E.4 of this catalogue. For theweakest short-circuit value it is necessary to verify thatthe protective devices as the Record PlusTM circuitbreaker trips before the conductors reach thementioned limits. On using circuit breakers it isgenerally sufficient to check if the weakest short-circuitcurrent trips the short-circuit protective element of thedevice.

Permissible thermal stress in conductorsFor insulated conductors and cables this is defined bythe formula:

t ≤ K2 S2

Ik2

Terminologyt = the short-circuit time in seconds k = a factor determined by the conductor in accordance with

HD384-5-54Ik = the weakest short-circuit current in AS = the conductor cross section in mm2

The table included here indicates the factor k forconductors with different insulation materials and thecalculated energy values for the conductor crosssections.

Weakest short-circuit current calculationsFor the most commonly applied network configuration,3 phase with neutral, the weakest short-circuit is thePhase to Neutral value. The network configuration determines the value of thiscurrent . Cases where the Phase to Earth or two Phasevalue is the weakest are also commonplace.Basically, the weakest short-circuit current isdetermined by the highest impedance loop in thecircuit that the breaker is protecting.Due to the simple fact that the impedance of this loopis mainly determined by the conductors included in thecircuit , their maximum length is limited. Anapproximation of the effect of the conductor or cablelength on the weakest short-circuit is possible by usingthe following formula:

Ikmin= 0.8 x Cmin x Uo x k1 x k2 x k3 AmpSqrt(R2 + X2)

TerminologyIkmin = Weakest short-circuit current0.8 = Assumed factor for the impedance of the upstream

networkCmin = Voltage factor; 0.95 assumedUo = Phase to neutral voltageX = Reactance of the conductors or cables in the circuit

reactance of multi core cables X in m /m 0.08R = Resistance of the conductors or cables in the circuit

based on the following basic data:23.69 m mm2/m. for copper cores*37.64 m mm2/m. for aluminum cores*

The values are in accordance with the Cenelec R064-003 documentfor calculating the weakest short-circuit current with circuitbreakers (warme state value)k1, k2 k3 = Correction factors, see next page

Personnel protection

If, in low voltage installations, a person makes contactwith two or more conductive materials/ surfaces with adifferent electrical potential he or she will risk apotentially dangerous electrical shock. This results in an electrical current flowing through thepersons body, the effects of which are indicated infigure 1 and the accompanying text . (source IEC 60479-1)

Zone Physiological effects

1 Usually has no reactions or effects. 2 Usually has no harmful effects. 3 Usually, no organic damage is expected.

Here the likelihood is present of muscular contractions anddifficulty in breathing. Reversible disturbances in theformation and conductance of impulses in the heart,including arterial fibrillation and transient cardiac arrestwithout ventricular fibrillation are possible. These effects increase with current magnitude and time.

4 In addition to he effects of Zone 3, the probability ofventricular fibrillation increases from 5% (curve c2) , to about50% (curve c3) and beyond 50% above curve c3. Increasingwith magnitude and time are pathophysiological effects ascardiac and breathing arrest, whilst heavy burns are possible.

If, in a low voltage installation, a person comes intocontact with an earthed part that has accidentallybeen connected to a live conductor, he or she will risk apotentially dangerous electrical shock. The level of voltage over the contact , and the length oftime that the person has to endure this contact can bedangerous. This so called 'Touch Voltage' must belimited to values that a human being can endurewithout physiological damage. The environment in which the fault occurs, dry orhumid, also plays a role in defining 'touch voltage'values. The IEC 60479-1 standard defines numerous touchvoltages or UL values.

50V AC........In a dry environment 25V AC........In a humid environment

The IEC 60479-1 defines that this so called 'TouchVoltage' must be disconnected within 5 seconds. Based on the environment and the associated 'TouchVoltage' maximum disconnect times are also specifiedfor a range of higher voltage value.

The term Personnel protection, as used here, entails theprevention of, or limitation of the effects of electricalshocks that occur during one of two possible contactscenario's, direct and indirect .

Direct contact

Caused by an accident in which a person comes intocontact with a live electrical conductor and a secondconductive part . Here the person in question becomesa part of the electrical circuit , the current in which isdetermined by the resistance of the earth and that ofthe human body.

How to protect against?The following methods can be used (source HD384)- The use of very low voltage systems as:

SELV (safe, extra low voltage), PELV (protective extralow voltage) and FELV (functional extra low voltage)

- Appropriate conductor insulation.- The use of mechanical barriers or that of enclosures

with the appropriate protection degree. (IP-)- Take the defined safety distances into account when

installing - The use of complementary protection, RCD's with a

sensitivity ≤ 30mA

Indirect contact

Caused when person comes into contact with anearthed part that has accidentally been connected to alive conductor. The level of voltage over the contact ,and the length of time that the person has to endurethis contact can be dangerous. This so called 'TouchVoltage' must be limited to values that a human beingcan endure without physiological damage.

How to protect against?The following concepts can be applied (source HD384)- The use of very low voltage systems as:

SELV (safe, extra low voltage), PELV (protective extralow voltage) and FELV (functional extra low voltage)

- Automatic disconnection of the power supply to theinstallation, or a part thereof.

- The use of materials that provide total insulation(class II)

- The use of a non conductive environment , i.e. Allexposed conductive parts cannot be accessed ortouched in normal operational conditions. Here the use of protective conductors is prohibited,whilst floor and walls must have a certain insulationresistance. (Un<500V AC, 50 kOhm; Un >= 500V AC, 100 kOhm.)

- The use of equipotential bonding or links. These toavoid potential differences between normally non-conductive materials/surfaces. These may not beconnected to earth.

- The use of LV/LV transformers with insulatingproperties.

Record PlusTM circuit breakers ,used to protect against direct ,or indirect contact

As moulded case circuit breakers, Record PlusTM haveproperties that automatically forfill a number of therequirements concerning direct and indirect contact .When installed correctly, with the appropriatecover/trim/front plates the device itself offers a highprotection degree of up to IP40 whilst the mouldedcase housing construction ensures a class II protection.

Direct contactThey can be equipped with RCD's of 30mA that arerequired as a complementary protection.

Indirect contactIdeally suited to be used as a device to allow automaticdisconnection of the supply of a part or a fullinstallation. This making use of one of three availableprotection devices.

- A short-circuit protection that can be set over a widerange and normally can be set to detect most earthfault currents.

- An optional RCD device that can detect earth faultcurrents down to extremely low levels.

- The larger frame size can be equipped with a groundfault protection device that can be set to detectmedium to low earth fault currents.

Protection against indirectcontact by automaticdisconnection of the powersupply

Use of the automatic disconnection of the powersupply concept requires that a number of elements istaken into account in a coordinated manner, i.e.:

- The characteristics of the network (earthing system - TT, IT, TN as described).

- The properties of the protective conductors.- The tripping threshold and disconnect time of the

protective device.- The properties of the environment.

This to ensure that the touch voltage does not exceedthe values of UL = 50V AC in a dry environment and UL = 25V AC in a humid environment and that highervoltages are disconnected within the perscribedmaximum disconnect time.

TT system characteristics

One point of the power supply is connected to earthwhilst all conductive parts in the installation areconnected to electrically independent earth electrodes.

O2 Power supply earthing (RN)

O3 Low voltage installation, consumer portion.

O4 Equipment present in installation.

O5 Exposed conductive parts/surfaces.

O6 Installation earthing. (RA)

O7 Optional RCD device.

If a fault to earth or insulation fault occurs, a circuitcomes into being, in which the current runs through thelive conductor that has caused the fault and the twoearth electrodes RA and RB. On indirect contact thetouch voltage UL is directly dependant on the value ofthe local earth electrode RA and the resistance of theprotective conductor by which it is connected. The following formula is valid:

RA x IA ≤ UL

RA = Resistance of local electrode and it's connecting protective conductor.

IA = With circuit breakers the short-circuit protective element of the device (magnetic operating threshold of the protective device)

Due to the very low values of RA required by theapplication of this rule the use of RCD's (see tablebelow) is widespread, and mandatory in severalEuropean countries. (IA is then replaced by the Idn ofthe RCD)

Remark : a TNCS system is not depicted

If a fault to earth or insulation fault occurs, a circuitcomes into being, in which the current runs through thelive conductor that has caused the fault and theprotective conductor (PE or PEN). The fault circuit has avoltage equal to the phase to earth voltage U0 of thesystem. On indirect contact the touch voltage UL is notexceeded if the following conditions are met

Zs x IA ≤ U0

Zs = Impedance of the fault circuit .IA = The operating threshold of the protective

device, that warranties a total disconnection time dependant on the phase to earth system voltage. (see table insert)

U0 = The phase to earth voltage of the system.

If the ZS value reaches high values due to long cableruns the use of RCD's is allowed. (IA is then replaced bythe Idn of the RCD).

A second option is the use of a ground fault device.In all cases the Interruption of the protective conductoris prohibited.

IT system characteristics

The supply is isolated from earth or connected to earthby means of an impedance of a relatively high value.The conductive parts in the installation are connectedto earth electrodes.

O1 Power supply.





O6 Impedance for insulation from earth.

O7 Insulation monitoring device + surge protection


On the first fault to earth or insulation fault in an ITsystem, the protective device does not need to react .Here no fault circuit to earth exists and no potentiallydangerous contact can occur. However, depending on the location of the fault toearth the first fault modifies the system from anisolated IT into a non isolated TN or TT system.To indicate that the IT system is no longer functionalthe use of insulation monitoring devices providing avisual and sonorous alarm of the event is necessary.With the first fault still existing, a second fault to earthmust cause an automatic disconnection of the supplythat must meet the conditions and formulae set out forTT and TN systems indicated here. The possible distribution of a neutral within the systemdoes modify the allowed disconnection times asindicated in the table below.

Required calculations in TN andIT networks

In both the IT and TN network configuration it isnecessary to verify that the protective device willinterrupt the circuit within the defined disconnectiontime. Here the worst case scenario needs to be takeninto account and the weakest possible current flowingin the circuit , on a insulation or earth fault must bedefined (The fault current If ).

Here it is also necessary to establish that the protectivedevice will disconnect within the time limits defined forthe different phase to phase and phase to neutralnetwork voltages, at this current level (Id). To determinethe fault current , the voltage of the circuit and it'simpedance must be known. The circuit impedance beingthat of the upstream installation and that of the live andprotective conductor.

Use of Record PlusTM breakers inthis application

Circuit breakers of the Record PlusTM type disconnectwithin 0.1 seconds on their magnetic threshold (Im onthe electromechanical device) and within 0.2 secondson their ST device (Im on the SMR1 electronic device*).To assure a disconnection that meets the requirementsthe circuit fault current Id must be higher than the Imvalue.With the Im value and the system voltage it is nowpossible to calculate the maximum ZS value of the faultcircuit . This is mainly made up of the electricalconductors in the circuit , therefore these calculationsresult in a maximum cable run length.

Formula for calculating the cable run length.

Lmax= 0.8 x Cmin x x Uo x k1 x k2 x k3 meters{2 x [= (R2 + X2)]} x (Im x kt)

Selectivity/Discrimination

Fig. 1 depicts a typical distribution network. Hereoutgoing circuits are designed for the current load andthe characteristics of the equipment within the circuit .Outgoing circuits that protect a certain area are placedtogether in panels or form groups within panels.Typically this group of circuits is protected by a second,similar device, the characteristics of which aredetermined in the same manner. This system can beextended to a multiple level distribution network.In case of a fault it is necessary that the device nearestto the fault reacts while all others remain closed. This capability is called discrimination (UK) or selectivity(USA and Europe). If this requirement is not met, a fault(F) in one arm of the distribution system will cause anumber of upstream protection devices wired in series totrip. Thus a minor fault in a socket outlet of a circuit cancause whole floors, buildings or building complexes to becut off from the power supply.

Record PlusTM breakers are specifically designed todiscriminate. By introducing Record PlusTM. GE sets a newstandard in circuit breakers by offering total selectivityfor all normally proportioned distribution systems.

EN 60947-2 amendment 1, app. A defines under“Coordination” that discrimination/selectivity may bepartial up to a pre-defined current limit (Is).Discrimination is considered total when the currentlimit is equal to the rated short-circuit breakingcapacity (Icu or Ics) of the downstream device. Discrimination/Selectivity is determined by comparingthe time it takes an upstream device to react at aspecific current value and - again - comparing this tothe time it takes a downstream device to clear the faultat the same current level. (see Fig. 2) The comparison ofthese two time spans can be used to define whetherdiscrimination is present or not . We have simplified this comparison by applying amultiplication factor between downstream andupstream devices. With the values indicated in thetable we can guarantee discrimination. (see page E.15)

3D discrimination

Record PlusTM downstream-protection-device breakerslimit the energy and current in the protected circuit in alimited time frame. The use of relatively minor timedelays in the short-circuit protection of the upstreambreaker, allows the Record PlusTM line of circuit breakersto achieve total discrimination. Fig. 3 depicts thiscomparison technique. In this graph the Grey areaindicates the time and current values the downstreambreaker allows to flow in the circuit . The coloured areadepicts the current- and energy-reaction level of theupstream device within a certain set time frame.

How to determinediscrimination/selectivity withRecord PlusTM (and associateddevices)

Table D1 to D5 (page E.16-E.19) indicate thediscrimination levels that can be achieved with Record PlusTM and associated devices. Wherediscrimination is partial the selectivity limits in kA (Is) arementioned in kA. Where a "T" is found in the tables, this indicates total

discrimination up to the highest breaking capacity of thedevices. These discrimination/selectivity limits are only valid if theratio between the current settings, ratings or timesettings of the upstream and downstream breaker areequal or higher than the factor indicated here.

Back-up protection

One of the operational requirements for a protectivedevice is that its rated short-circuit breaking capacityIcu or Ics is either equal or greater than the prospectiveshort-circuit current at the point where it is installed. EN 60384 defines one exception to this in clause 434:

The upstream device must posses the necessary ratedshort-circuit breaking capacity at its point of installation.The upstream device must coordinate with thedownstream device in a manner that will limit the energyand short-circuit values to levels that the downstreamdevice can handle.

Use of current limitation

Installing an upstream device that limits the prospectiveshort-circuit values will enable the user to place adownstream device with a lower breaking capacity. The coordination between the two devices allowsexcellent breaking capacity at a low cost .

Record PlusTM

The Record PlusTM rotating dual contact configurationlimits the energy and current values of prospective faultsto extremely low values. This key design feature allowsthe use of cost-effective downstream devices whilemaintaining overall system protection.Back-up protection is inherently „unselective“ or „non-discriminating“. That means that the upstreamdevice must react first in order to protect thedownstream device. However, the Record PlusTM devicesare so current limiting that the current and energyvalues present in the circuit do not trip the upstreambreaker. Please refer to the details on „Selectivity Plus“for a description of this technique.

The tables B1 and B2 are in complete accordance withthe EN 60947-2 requirements and have been verifiedthrough experiment where necessary. They provide datafor the Record PlusTM breaker and the other GE Power Controls/Industrial Systems product lines. The values are only applicable for the devicesmentioned.

Back-up protection requires an upstream device to open inorder to protect the downstream device(s) before the down-stream devices can be damaged. For continuity of service it isdesirable that the upstream device remains closed and thatonly the downstream device closest to the fault reacts.The Record PlusTM family of breakers resolves this paradox: thebreakers are so current limiting that let-through energy andcurrent are not sufficient to operate the upstream breaker.The result discrimination to current levels that are higher than

the rated short-circuit breaking capacity of the downstreambreaker.Tables DB1 to DB5 provide the data for the Record PlusTM breaker line used in combination with theElfaPlus, Surion and MPact protection devices. The values inthe table are in kA and indicate the results of the SelectivityPlus technique. Before the slash the discrimination limit in kA, after the slashthe back-up protection value at 400V in kA (e.g. 50/80).

Coordination with loadbreakdisconnect switches

Record PlusTM circuit breakers excel in theircharacteristics as current and energy limitingdevices. This allows one to use lighter and moreeconomical downstream busbar systems andswitchgear.

A frequently used combination is that of a Record PlusTM breaker, used as a protection andswitching device in the mains switchboard, and aDilos loadbreak switch, as an incomer, in adownstream, secondary switchboard. In thisapplication the Dilos needs to be able to withstandthe current and energy values on a short-circuitevent , this taking the limiting effects of theupstream breaker into account .

The table indicates the maximum prospectiveshort-circuit that the combination of an upstreamRecord PlusTM and a downstream Dilos or Record PlusTM in its switch disconnect variant (type Y) can withstand.

Protection of motor circuits

Protection of the electrical circuitThe motor circuit must provide the followingfunctionality:• Isolate the circuit from the network for maintenance.• Protect against short-circuits in the equipment ,

the starter and the cables within the circuit .• Protect against overloads in the equipment ,

the starter and the cables within the circuit .• Protect against faults specific to the motor within it's

application.Control of the motor in question, this covering starting,stopping, speed control etc.

StandardsThe requirements for circuits supplying a motor, ingeneral called "motor starters", can be found in the IEC 60947-4-1. To define the components for isolation,overload and short-circuit protection the followingelements must be defined:• Depending on the type of electrical motor and it’s

operational requirements, four motor utilizationcategories have been defined. These have an impacton the characteristics of the control element withinthe circuit . These so called AC classes are depicted inthe table on the right .

• The required trip curve class of the overloadprotection, this depending on the motor application,the classes 10A, 10, 20 and 30 are normally used, the requirements for which are indicated in the table.

• Isolation and safety during maintenance. Use of the Record PlusTM breaker here provides anenhancement of the present standard requirementfor POSITIVE OFF adding in a POSITIVE ONindication.

The combination of thesedevices must be coordinated to ensure theefficiency and an optimal protection of the motor.Here, the protection of such circuits stronglydepends on the operational requirements, as the application for which the motor is used, therequired starting frequency, the required servicelevel and the applicable safety standards.

The unique properties of the Record PlusTM breakerallow GE to offer solutions meeting the higheststandards. For this reason all tables published hereonly refer to coordination type 2.

This entails that the GE equipment meets thefollowing standards• No or minor weldings of the contactors after testing;

contact separation is simple and easy• The switchgear and controlgear are fully operational

after the tests indicated here.

Option 1

Magnetic only circuit breaker as the short-circuit protection device.

Contactor for control purposes.

Separate thermal relay for class 10 or class 30 as overload protection.

Coordination type 2 test sequence

Option 2

Electronic circuit breaker as the short-circuit and Overload protection device.

Contactor for control purposes.

After power is disconnected (circuit interruption after a fault) thebreaker has no thermal memory function. This implies that after anoverload, immediate breaker reset and re-energization of thecircuit is possible. In order to prevent this a Long time module can be utilized thatcloses a contact on an overload just before the breaker trips. Thisallowing the contactor in the circuit to be de-energized and a externalthermal memory to be initialized, before the breaker trips.

The sketch here depicts the long time module as anoptional add on in the circuit diagram. Here the breakeris the short-circuit protection device AND a backupoverload protection. If the contactor fails to open on along time module signal the breaker will trip.

• After this test the original characterstics of the contactor and thermal relay MUST remain unchanged.

• After this test the short-circuit protection must trip within 10 ms at a fault current ≥ 15 x In.

Short-circuit test

This value which is generally ≤ 50kA is used to check the coordination of the devices used in the motor starter circuit. For each combination with Record PlusTM breakers this value is mentioned in the tables on pages E.28, 29, 30, 31, 32 and 33. After a test with this current the following conditions must be met:• No or minor weldings of the contactors after testing; contact

separation is simple and easy• The switchgear and controlgear are fully operational after the test.

CoordinationThe standards require tests to define thecoordination between the devices within the motorstarter. Depending on the state of the componentsafter the test two coordination classes 1 and 2have been defined.

Solutions with the Record PlusTM breakerMotor starters are compiled with a number of GE components. This is to offer the requiredfunctionality of the motor starter circuit and toallow a choice in the execution thereof.

Protection of LV/LV transformers

Transformers generally produce a very high inrushcurrent . The crest value of the first half cycle mayreach values of 15 to 25 times the effective ratedcurrent .For a protective device capable of protecting theseunits this must be taken into account . Manufacturersdata and tests have indicated that a protective devicefeeding a transformer must be capable of carrying thefollowing current values without tripping (see graphinsert).

Record PlusTM circuit breakers have been designed tocope with this kind of phenomenae. The adjacent tableindicates the types to select , based on the breakercharacteristics, the transformer ratings and the abovementioned inrush current prognoses.

Protection of capacitor banks(power factor improvement units)

For circuit breakers and particularly for the Record PlusTM device, designed to offer high makingand breaking capacities under adverse conditions, theswitching of capacitor banks has little to no effect onthe breaker, its characteristics as a protective device, or on its lifespan.

However, the current flowing in the circuit can trip acircuit breaker and a capacitor load displays certainanomalies. In a circuit with capacitors the maximumcurrent flow in the circuit cannot be assumed to be thecalculated capacitor current only. The effective valuemust be increased due to harmonic content (a factornormally taken as 30%) and an allowance for thetolerances in the capacitance of the unit itself. (10% assumed).

In order to protect these devices without running intoregular nuisance tripping due to overloads please referto the adjacent table in which the correct Record PlusTM

breaker is specified to protect and switch the indicatedcapacitor banks at several different voltages.
