OPERATION DISPLAY MECHANISM, CIRCUIT BREAKER, COMPOUND BREAKER, AND DISPLAY MEMBER

摘要

This operation display mechanism (50) is provided with a display member (51) that displays the operating state of a circuit-breaker circuit. Said display member (51) displays when interruption-mechanism contacts are opened or closed by a handle or when said contacts are pulled apart by a tripping device due to the circuit having reached a prescribed operating state. The display member (51) is provided with a spring engagement part (56) and an engagement protrusion (58). The spring engagement part (56) can engage with an interruption mechanism on a right pole of a ground-fault circuit interrupter, and the engagement protrusion (58) can engage with an interruption mechanism on a left pole of said ground-fault circuit interrupter.
