Abstract
The invention relates to a miniature circuit breaker with a failure tripping indicating device. The main problems that when an existing miniature circuit breaker is used, whether the circuit breaker breaks or not is difficult to judge, therefore an operator is very likely to be misguided, and security incidents are caused are solved. An observation window is arranged at the position, on the top left of a jump pin, of a shell and corresponds to the jump pin. A failure indicating piece is matched in the position, below the observation window, of the shell in a sliding mode and corresponds to the observation window. A pushing part is matched on the jump pin in a linkage mode, wherein when tripping happens, the pushing part presses the failure indicating piece toward the first direction corresponding to one side of the observation window in an ejecting mode. A push-backing part is arranged on a supporting piece and presses the failure indicating piece toward the second direction correspondingly opposite to the first direction in an ejecting mode when the circuit breaker is switched in. An elastic plate is arranged on the failure indicating piece. A limiting convex shoulder is arranged on the shell and matched with the elastic plate in an elastic mode, and therefore the one-way limiting match that the elastic plate and the limiting convex shoulder are clamped in an elastic mode to enable the failure indicating piece to shift toward the first direction when a failure recovers is achieved. The miniature circuit breaker with the failure tripping indicating device has the advantages of being simple in structure, convenient to use, good in stability and high in safety.
