摘要： A circuit breaker (10) with trip indicator assembly (40) for indicating the trip status of the circuit breaker (10). The trip indicator assembly (40) includes a spring powered shaft (50) movable between a cocked position and a trip position in which the spring powered shaft (50) protrudes through the housing (12) of the circuit breaker (10) to indicate the trip status. The shaft (50) is operatively connected to a trip actuating mechanism (26) of the circuit breaker (10) so as to actuate the shaft (50) in response to the trip actuating mechanism (26) actuating an operating mechanism (22) of the circuit breaker (10). A lost motion coupling (72) is provided to assure that the trip indicator assembly (40) is not actuated until after actuation of the operating mechanism (22). A bell alarm switch assembly (82) for signalling the trip status of the circuit breaker (10) may be operatively connected to the trip indicator assembly (40).
