ABSTRACT:
A circuit breaker includes a circuit breaker frame and a trip unit. The circuit breaker frame includes a housing, a line terminal, a load terminal, separable contacts electrically connected between the line terminal and the load terminal, an operating mechanism structured to open and close the separable contacts, and a latch cooperating with the operating mechanism to open the separable contacts when actuated. The trip unit includes a housing, a line end terminal electrically connected to the load terminal of the circuit breaker frame, a load end terminal, and a fuse including a plunger. The fuse is housed by the housing of the trip unit and is electrically connected between the line end terminal and the load end terminal. An interface mechanism is structured to actuate the latch of the circuit breaker frame when the interface mechanism is engaged by the plunger of the fuse.
