Claims

[Scope of utility model registration request]

In a circuit breaker in which a bimetal for overcurrent detection is attached to a slider housed in a case, and the bimetal short-circuits between two fixed contacts provided in the case in the ON position, the circuit breaker is configured to correspond to each fixed contact. A circuit breaker in which a movable contact provided on a bimetal is elongated vertically with respect to the sliding direction and has a concave portion formed in the center, and the movable contact contacts a fixed contact with two contact surfaces formed apart in the sliding direction. mosquito.
