41PR-6803 MOLDED CASE CIRCUIT INTERRUPTER TRIP INDICATING HANDLE ABSTRACT OF THE DISCLOSURE An operating handle assembly for molded case circuit inter- rupters is robotically assembled to the circuit breaker operat- ing mechanism without requiring any auxiliary fastening means. A visual access slot in the circuit breaker cover allows the condition of the circuit breaker contacts to be visually ascer- tained by means of colored indicia carried by the operating handle skirt. A slidably mounted handle shutter cooperates with the operating handle to prevent egress of arc exhaust gases in the event the circuit breaker contacts are closed or opened during overcurrent conditions when the circuit breaker is in- stalled within an industrial power distribution circuit.
