Description
MotorCircuit
Protector
The Westinghouse line of Motor Circuit Protectors (HMCP) are
instantaneous (magnetic only) trip current limiting type circuit breakers.
They may be supplied by Allen-Bradley in Bulletin 500 Line NEMA Sizes 0
through 5 combination starters. The particular circuit breaker (trip range)
supplied with a combination starter depends on the horsepower and voltage
that was specified when the device was ordered. Table 1 lists the various
combinations of circuit breakers and starter sizes. When using the table, be
sure to refer to the line that applies to your equipment.

The ELC current limiter is an attachment that bolts to the load end of the
HMCP to provide increased interrupting capability. It is available for NEMA
sizes 0 through 4. The current limiter is coordinated with the HMCP so that
normal short circuits will be cleared automatically by the HMCP, opening all
3 poles.
The current limiter will only clear the very high level faults at approximately
50 or more times the continuous rating of the HMCP. At the same time a
sufficient level of current let-through will magnetically trip the HMCP to
prevent single-phasing.
Each pole of the current limiter is equipped with a spring loaded indicator to
quickly identify the phase(s) on which the fault has occurred. Circuit
problems must be corrected before attempting to restore service.

Consult the Sales Department at Milwaukee for combination starters not listed in the table.
Maximum Available Amperes is 10,000 when using a 250 Amp HMCP for NEMA Size 4.
A push-to-trip mechanism is used to trip the HMCP. Depress the red button
located on the circuit breaker cover. This mechanical pressure causes a
plunger to engage the trip bar which then rotates and results in the HMCP
contacts opening.
Circuit Breaker Trip Settings
Field adjustment on the trip setting of the HMCP is dependent upon the
motor full load current. Allen-Bradley recommends the selection of trip
settings that are approximately 10 times the motor nameplate’s full load
current. The trip setting is adjusted by rotating a cam lever to the appropriate
position. The positions are labeled A through H for 150A frame and A
through I for 250A and 400A frames. The procedure for setting the HMCP
is:
1. Place the circuit breaker operator in the “OFF” position.
2. To select setting, use a screwdriver to depress the adjustment pointer and
mm in the direction indicated by the curved arrow.
3. Verify that the circuit breaker will not trip during motor starting. If the
circuit breaker trips on starting, turn the pointer clockwise to
successively higher positions until the circuit breaker does not trip on
starting.
NOTE: The trip setting of the circuit breaker must never exceed 13 times the
motor full load current. Refer to the National Electrical Code and the
Canadian Electrical Code for information.

ATTENTION:
The horsepower ratings and corresponding trip settings for
each circuit breaker in the table are only valid when the motor
running overcurrent protective device (overload relay) in the
combination starter is an Allen-Bradley Bulletin 592 or
Bulletin 593 overload relay with properly selected heater
elements.
When correctly selected, this combination of equipment will
permit coordinated overcurrent protection in the motor branch
circuit for motors rated for continuous duty and can provide
protection against damage due to short circuits and ground
faults as defined in the National Electrical Code and Canadian
Electrical Code.
The tripping of the circuit breaker indicates the interruption of
a high fault current. In order to maintain protection against
fire and/or shock hazard, the current carrying parts of the
combination starter should be examined and replaced if
damaged. (Refer to NEMA Standards Publication ICS 2.2
titled: “Maintenance of Motor Controllers After a Fault
Condition” - also published as NEMA Standard Publication
No. ICS 2, Part ICS 2-3022
