Trip indicator and signalling switch assembly |
摘要 |
A circuit breaker with trip indicator assembly for indicating the trip status of the circuit breaker. The trip indicator assembly includes a spring powered shaft movable between a cocked position and a trip position in which the spring powered shaft protrudes through the housing of the circuit breaker to indicate the trip status. The shaft is operatively connected to a trip actuating mechanism of the circuit breaker so as to actuate the shaft in response to the trip actuating mechanism actuating an operating mechanism of the circuit breaker. A lost motion coupling is provided to assure that the trip indicator assembly is not actuated until after actuation of the operating mechanism. A bell alarm switch assembly for signalling the trip status of the circuit breaker may be operatively connected to the trip indicator assembly.
