breaker interface module.  If IMPACC Series III software

is part of the system, this too can be used to set the trip 

unit settings.  Refer to the user manuals for details.

MANUAL OPERATION

Manual operation of the circuit breaker is controlled by

the circuit breaker handle and the PUSH-TO-TRIP but-

ton in the trip unit.  The circuit breaker handle has three

positions, two of which are shown on the cover with

raised lettering to indicate ON and OFF.  On the handle, 

ON, OFF, and trip are also shown by a color-coded strip 

for each circuit breaker handle position: red for ON,

white for tripped, and green for OFF (see Figure 3-1).

Circuit Breaker Reset

After a trip operation, the circuit breaker is reset by mov-

ing the circuit breaker handle to the Reset (extreme 

OFF) position. It is not necessary to press the reset

button before resetting the breaker.  The reset button 

affects only the cause of trip indicator LED’s. It does not 

affect the operation of the circuit breaker itself.

No circuit breaker should be reclosed until the

cause of trip is known and the situation rectified. 

PUSH-TO-TRIP Button

The PUSH-TO-TRIP button operates the circuit breaker

tripping function and may be used to periodically exer-

cise the operating mechanism.  The button is designed

to be operated by a small screwdriver.

INSPECTION AND FIELD TESTING

Series C molded case circuit breakers are designed to

provide years of almost maintenance-free operation. 

The following procedure describes how to do a limited 

amount of field inspection and testing of a circuit break-

er.

Inspection

Circuit breakers in service should be inspected periodi-

cally. The inspection should include the following

checks 4-1 through 4-7.

WARNING

THE VOLTAGES IN ENERGIZED EQUIPMENT CAN

CAUSE SEVERE PERSONAL INJURY OR DEATH.

BEFORE INSPECTING THE CIRCUIT BREAKER IN

AN ELECTRICAL SYSTEM, MAKE SURE THE CIR-

CUIT BREAKER IS SWITCHED TO THE OFF POSI-

TION AND THAT THERE IS NO VOLTAGE PRESENT 

WHERE WORK IS TO BE PERFORMED.

SOME COMMERCIAL CLEANING AGENTS WILL

DAMAGE THE NAMEPLATES OR MOLDED PARTS. 

MAKE SURE THAT THE CLEANING AGENTS OR

SOLVENTS USED TO CLEAN THE CIRCUIT BREAK-

ER ARE SUITABLE FOR THE JOB.

4-1.

Remove dust, dirt, soot, grease, or moisture from

the surface of the circuit breaker using a lint-free dry

cloth, brush, or vacuum cleaner.  Do not blow debris into
