Moulded Case Circuit Breakers16-2500 Amperes for IEC 947-2 Applications
The Most Logically Designed
Contact Assembly
The flexibility and outstanding per-formance characteristics of Series C Circuit Breakers are made possible by one of the most logically designed contact assemblies in circuit breaker history. Based on previously patented Westinghouse contact conductor designs, the Series C contact assembly creates a high-speed “blow-open” action when it confronts the electrome-chanical forces produced by high-level fault currents.
Series C Circuit Breakers are oper-ated by a toggle-type handle that is mechanically trip-free from the han-dle so that the contacts cannot be held closed against short circuit cur-rents. Tripping due to overload or short circuits is clearly indicated by the position on the handle. This remarkably fast and dependable contact action is designed to enhance safety.
Thorough In-Plant Testing
The quality, dependability, and relia-bility of every Series C Circuit Breaker is assured by a thorough program of in-plant testing. Two calibration tests are conducted on every pole of every circuit breaker to verify the trip mech-anism, operating mechanism, conti-nuity, and accuracy.
ISO Certification
Series C Circuit Breakers are manu-factured in ISO certified facilities.
More Interrupting Capacity
in Less Space
Series C Circuit Breakers are physi-cally and electrically interchangeable with the “Classic” standard line of Westinghouse moulded case circuit breakers. This means Series C Break-ers are ideal for upgrading equip-ment designs and retrofitting existing installations.
Current Limiting Characteristics
All Series C Circuit Breakers are cur-rent limiting because of their high repulsion contact arrangement and incorporation of state-of-the-art arc extinguishing technology.
Operating Mechanisms
Series C Circuit Breakers have, in their basic version, a toggle handle operating mechanism, which also serves as switching position indica-tor. As well as ON and OFF, the fur-ther position TRIPPED is possible.
The toggle handle snaps into the TRIPPED position if the breaker is tripped by one of its overcurrent, short circuit, shunt or undervoltage releases. Before the circuit breaker can be reclosed following a trip-out, the toggle handle must be brought beyond the OFF position (RESET). The circuit breaker can then be reclosed.
As an additional switching position indicator for F- to R-Frame circuit breakers, there are two windows on the right and on the left of the toggle handle, in which the switching state is indicated by means of the colours red, green and white corresponding to the ON, OFF and TRIPPED posi-tions respectively.
General Information
Series C Moulded Case Circuit Breakers provide increased perform-ance in considerably less space than standard circuit breakers or compa-rable fusible devices. Reduced sys-tem costs can also be realized because Series C Circuit Breakers are used in series rated systems, allowing the use of lower interrupt-ing circuit breakers downstream.
Series C Circuit Breakers meet appli-cable IEC 947-2 standards, have been assigned ultimate and service interrupting ratings per IEC 947-2, and employ adjustable thermal and adjustable magnetic trips.
The Series C family includes seven frame sizes in ratings from 100 to 2500 amperes. Each frame size offers a choice of several interrupt-ing capacities up to 100 kA at 415 volts ac (200 kA at 240 volts ac). This provides greater design flexibility than ever before possible while also helping to save space.
Series C Circuit Breakers virtually eliminate the need for redesign and they can be used to replace older circuit breakers in the same panel-boards, feeder pillars, busbar trunk-ing tap-offs, individual enclosures, machine tool control panels, and motor control centres. In most cases, the same connecting straps, studs, and handle mechanisms can be retained and used.
Standard calibration is 40
°
C. For applications in high ambient tem-perature conditions, 50
°
C factory calibration is available.
Series C Circuit Breakers are also provided for dc applications. Inter-rupting ratings of 35 kA for the 600 ampere frame have been achieved for three-pole breakers in series at 600 volts dc.

Electrical Characteristics
DC Switching Duty
The F- to L-Frame circuit breakers are also suitable for switching dc currents.
The N- and R-Frame circuit breakers, FWMP, KWMP, and LWMP circuit breakers for motor protection are not suitable for dc currents due to the solid state overcurrent release system.
For switching dc currents, however, the maximum permissible dc voltage per conducting path has to be con-sidered.
For voltages higher than 250 volts, the series connection of two or three conducting paths is required.
As the current has to flow through all conducting paths so as to maintain the thermal tripping characteristics, the following circuit arrangements are recommended. With dc, the trip values of the instantaneous short circuit release (“n” release) are increased by 30 to 40%.
For 3- and 4-Pole Circuit Breakers
Proposed Circuit Maximum Permissible VDC Ue
Remarks
250 VDC Double-pole switching.
If there is no risk of an earth fault, or if any earth fault which occurs is immediately eliminated (earth fault monitoring), the maximum permissible dc voltage can be 600 volts.
440 VDC Double-pole switching (earth system).
The earthed pole must always be assigned to the individual conducting path, so that two paths are always in series in the event of an earth fault.
600 VDC Single-pole switching (earthed system).
Three conducting paths in series. The earthed pole must be assigned to the nonswitched conducting path.
750 VDC Single-pole switching (earthed system).
Four conducting paths in series. The earthed pole must be assigned to the nonswitched conducting path.

Multi-Function Electronic Trip Units for All Applications
Digitrip™ RMS Trip Units
True RMS Sensing
Digitrip RMS Trip Units utilize our proprietary SuRE™ Chip and SuRE Plus™ Chip microprocessor-based intelligence to provide true rms sensing, permitting increased accu-racy and reliable system protection. True rms sensing is not susceptible to nuisance tripping when wave-forms containing high harmonic currents are present.
Digitrip RMS 310
Digitrip RMS 310 Electronic Trip Units are available with Series C Circuit Breakers K-, L-, N- and R-Frames 63 through 2500 amperes. Digitrip RMS 310 Trip Units are available in four styles with either fixed or adjustable rating plugs which establishes the continuous ampere rating of the breaker.
Rating Plugs
Digitrip RMS 310 Trip Units incor-porate rating plugs that are inter-changeable within a specific circuit breaker frame. This provides the user with versatility when establishing the continuous current rating of a breaker. Rating plugs are frequency sensitive and may be specified for 50 / 60 Hz applications. Both fixed and adjustable rating plugs are avail-able, providing further flexibility when applied to selectively coordi-nated systems.
Note: Digitrip RMS rating plugs are not interchangeable with SELTRONIC™ rating plugs.
Curve Shaping
When selectively coordinated sys-tems are called for, Digitrip RMS 310 will provide a cost-effective solution for a variety of applications.
The standard Digitrip RMS 310includes an adjustable short timepickup setting encompassing an I2tramp function which provides thebasic LS curve shaping function.
The optional Digitrip RMS 310 provides additional flat response short time delay adjustments on an instantaneous setting to provide LSI curve shaping capability.
Both Digitrip RMS 310 Trip Units are available with ground fault pickup and flat response ground fault delay which provide the trip unit with full function LSG and LSIG curve shap-ing flexibility.
Digitrip RMS 310 Trip Units can effectively coordinate with both sophisticated upstream power breakers as well as downstream thermal magnetic breakers…making Digitrip RMS 310 Trip Units the cost-effective reliable choice for selec-tively coordinated systems.
Thermal Memory
All Digitrip RMS Trip Units incorpo-rate a long delay and, when ordered with ground, a ground fault thermal memory feature. Thermal memory prevents the system from cumula-tive overheating due to repeated overcurrent events that may occur in quick succession.
Digitrip RMS 510, 610, 810, and 910
Digitrip RMS 510, 610, 810, and 910 Trip Units are available with Series C R-Frame Circuit Breakers 800 through 2500 amperes. Digitrip 510, 610, 810, and 910 Trip Units provide unparalleled system protection with fixed rating plugs to establish the continuous ampere rating of the breaker.
Curve Shaping
Digitrip RMS 510, 610, 810, and 910 Trip Units are available with up to nine curve shaping choices achieved by adjusting up to seven switches on the front of the unit for optimum system coordination. Maximum curve shaping flexibility is provided by dependent long and short delay adjustments that are long delay pickup (Ir) based, depicted on the front of the unit by the blue portion of the time-current curve.
Additional coordination capability can be provided by utilizing the short delay and ground fault zone selective interlocking features avail-able on these trip units.

System Diagnostics
All four Digitrip RMS models of trip units provide long delay, short delay, instantaneous, and ground fault cause of trip LEDs on the front of the unit. Digitrip RMS 610, 810, and 910 also offer a magnitude of trip information as well as remote signal contacts for improved system diagnostics.
System Monitoring
Digitrip 610, 810, and 910 Trip Units have the capability to monitor phase currents as well as neutral or ground currents. This information is dis-played on a large digital display mounted on the unit.
Digitrip RMS 810 and 910 Trip Units can also provide the user with power and energy monitoring capability. Peak power demand, present power demand, and total energy as well as forward and reverse energy can be monitored with this unit.
Digitrip RMS 910 Trip Units have the additional capability of monitoring line to line voltage as well as system power factor. Both parameters are displayed in the digital display win-dow and are supported by LEDs to indicate which parameter is being displayed.
Harmonics Monitoring
Digitrip RMS 910 Trip Units are capa-ble of displaying values of current harmonics in the digital display window. Percentage of harmonic content can be monitored for each phase, neutral or ground, up to the 27th harmonic. Additionally, a total harmonic distortion value can be calculated and displayed.
Communications
Digitrip RMS 810 and 910 have built-in communications options to allow all protection, monitoring, and con-trol information to be transmitted back to a central location via the Cutler-Hammer IMPACC System.
Field Testing
Integral field testing capability is provided on all 510, 610, 810 and 910 Trip Units. No additional test set is needed to perform both trip and no trip field testing.

Selection Guide and Ordering Information
The Cutler-Hammer general purpose rotary handle mechanisms are suita-ble for use with NEMA 1, 3R, 4 and 12 fabricated enclosures. They are designed for use with Series C Circuit Breakers, Moulded Case Switches, and Motor Circuit Protec-tors (MCP).
Required for a standard application are the operating handle, shaft, and mechanism.
It may be mounted in either the hori-zontal or the vertical direction. The handle was ergonomically designed with extra clearance for “gloved hand” to operate. It may be pad-locked in the OFF position utilizing three padlocks. The handle is cast metal only.
The standard label on the operating handle indicates ON/Tripped/OFF/Reset.
The Flex Shaft type handle mecha-nism is an extra heavy-duty handle mechanism designed for mounting in flange-type enclosures. An oper-ating handle, flexible shaft, and mechanism are required for stand-ard application.
The handle can be locked in the RESET position with up to three padlocks. The handle is suitable for NEMA 1, 3R, 4, 4X, and 12 fabricated enclosures. It is supplied for mount-ing in right-hand flange enclosures. The handle fits the industry standard cutout.
Eight lengths of shafts are available for use with the wide range of depths of various enclosures (3-feet through 10-feet). These choices ena-ble this mechanism to be mounted in various depth, width, and height enclosures. Note: when selecting the length of shaft, ensure minimum bending radius of 4-inches is main-tained to operate properly.

Remote Controlled Operating
Mechanisms
Series C Circuit Breakers (sizes 160 to 2000 amperes) can be equipped with motorized operating mecha-nisms for remote in-service closing and opening.
For normal remote opening, sole-noid operating mechanisms F- and K-Frames are available for circuit breakers and motorized operating mechanisms for J to R (sizes 250 to 2500 amperes) solenoid operating mechanisms and motor operators are always supplied with a locking device for padlocks. This device can be used for electrical and mechanical blocking of the operating mecha-nism. All remote operating mecha-nisms are equipped with a manual actuator for local operation.
Alarm Lockout
The alarm switches operate when the circuit breaker is tripped by a short circuit or overcurrent, but also when it is tripped by a shunt trip or undervoltage release.
Auxiliary Switches
Auxiliary switches are used for sig-nalling and control purposes. The various functions of the auxiliary switches (changeover) are shown in the top table to the right.
Shunt Trips
The shunt trip is used for remote tripping.
The coil of the shunt trip is rated only for short-time operation.
It is not permissible with the circuit breaker open to apply a continuous opening command to the shunt trip in order to prevent the breaker from closing.
This means that interlocking circuits with continuous commands may not be set up with shunt trips.
Undervoltage Releases
The circuit breaker cannot be closed until the undervoltage release is energized. If the release is not ener-gized, the circuit breaker can only perform an idle switching operation.
Frequent idle switching actions should be avoided as they shorten the endurance of the circuit breaker.

Tripping Characteristics
The operating values specified for the inverse time overcurrent releases (thermal overload releases, “a” releases) are mean values of the scatter bands of all setting ranges from the cold state and with uniform current loading of the conducting paths.
The tripping characteristics of the instantaneous (electromagnetic) short circuit releases (“n” releases) are based on the rated phase current I
n
which in the case of circuit break-ers with adjustable thermal overload releases is also the upper value of the setting range. With a lower set-ting current, a correspondingly higher multiple is obtained for the operating current of the “n” release.

Characteristics of the FWMP,
KWMP, and LWMP Circuit Breakers
for Motor Protection with Solid
State Overcurrent Releases
The tripping times of the inverse-time delayed overcurrent releases are only valid for the not preloaded (cold) state. At operating tempera-ture (after load with rated current), the tripping times are reduced to approximately 33%. After an over-current trip, the tripping times are reduced according to the tripping time characteristics (see figure below) so that cooling down for some minutes is required before restarting the motor. During the first minute after tripping, reclosing of the circuit breaker is blocked.

The circuit breakers shall meet or exceed all standards as defined in IEC 947-2. Electrical circuits shall be protected by Series C World Moulded Case Circuit Breakers asmanufactured by Cutler-Hammer.
Each pole of the one-, two-, and three-pole circuit breakers shall provide complete circuit overcurrrent protection by having inverse time and instantaneous tripping character-istics and, where applicable, be current limiting.
The circuit breaker shall be available in interruptingfamilies that provide 35-65-100 kA at 380-415 volts AC.
The circuit breakers shall be operated by a toggle-type handle and have a quick-make, quick-break, over-centre switching mechanism that is mechanically trip-free from the handle so that the contacts cannot be closed against short circuit currents. Tripping due to overload or short cir-cuits shall be clearly indicated by the position of the han-dle. The ON and OFF positions shall be clearly marked on the cover of the circuit breaker along with the international symbols I for ON and O for OFF on the handle, providing positive indication of the circuit breaker contact position. Additionally, a colour-coded indication of the circuit break-er contact position shall be provided: red for ON, green for OFF, and white for TRIPPED. An easily accessible Push-To-Trip button for mechanically exercising the trip unit shall be provided on the cover of each circuit breaker. All poles of a multi-pole circuit breaker shall be so constructed as to ensure simultaneous open, close, and trip operations.
Circuit breakers shall be completely enclosed in a high strength glass-polyester case.
Noninterchangeable trip circuit breakers shall be factory sealed; interchangeable trip circuit breakers shall have the trip unit sealed to prevent tampering. Ampere ratings shall be clearly visible from the front of the circuit breaker. Con-tacts shall be nonwelding silver alloy. Arc extinction shall
be accomplished by means of DE-ION
®
arc extinguishers consisting of metal grids mounted in an insulating support.
The minimum interrupting ratings of the circuit breakers shall be at least equal to the available short circuit current at the line terminals.
The circuit breakers can be applied in series rated applica-tions and subject to test data verification.
Circuit breakers in frame sizes 100 amperes through 250 amperes shall be equipped with thermal-magnetic trip units. Circuit breakers 400 amperes through 2500 ampere frame sizes shall be equipped with electronic trip units that are insensitive to changes in ambient temperature within the normal operating temperature range of the circuit breaker. The 400 ampere and 630 ampere frame sizes shall be designed to accept either thermal-magnetic or electronic interchangeable trip units.
Electronic trip units shall be rms sensing type and have unpowered thermal memory.
Circuit breaker ratings and modifications shall beindicated on the drawings.
Circuit breakers shall be of the inverse time and instan-taneous trip type as provided by thermal-magnetic orelectronic trip elements with either standard interrupting, high interrupting, or current limiting characteristics as required.
Moulded case circuit interrupters (motor circuit protec-tors) shall be of the instantaneous (magnetic) only type, providing instantaneous short circuit protection by means of a front adjustable trip unit.
Moulded case switches shall be of the same construction as the related listed circuit breaker and equipped with a factory sealed, nonadjustable, high instantaneous only short circuit protection.
Moulded case switches shall have no overload or low level fault protection provided and shall be marked with amaximum withstand rating denoting the type and level of upstream protection required. Moulded case switchesshall be listed per IEC 947-2.
Internally mounted accessories including alarm (signal)/lockout switches, auxiliary switches, shunt trips, andundervoltage released mechanisms shall be of the plug-in type and shall be listed for field fitting in circuit breakers which are not factory sealed.
Electrical operators for circuit breakers of the 400 ampere frame size and below shall be of the solenoid type with maximum five-cycle closing characteristics. Electricaloperators for circuit breaker frame sizes 630 amperes through 2500 amperes shall be of the motor driven type. All electrical operators shall be cover mounted. Allelectrical operators shall be listed for field installationper IEC 947-2.
Electrical characteristics of accessories shall be asindicated on the drawings.
Circuit breakers in the 160 amperes rating shall be sup-plied in one-, two-, three-, and four-pole models, as speci-fied on the drawings. Circuit breakers in ratings of 225 amperes through 1250 amperes shall be supplied in two-, three-, or four-pole models. The 2500 ampere circuit breaker is available in three- and four-pole models as specified on the drawings.
Accessory wiring shall be brought out through the side or rear of the circuit breaker, or be connected to a terminal block mounted on the side of the circuit breaker, as speci-fied. The ability to route accessory wiring to the opposite side of the circuit breaker through a trough in the base shall be provided.
Circuit breakers shall be provided with uniformly designed nameplates to clearly indicate the type, rating, listing/recognition/certification marks, accessory details, andother information defined in IEC 947-2.
