Claims

[Scope of utility model registration request]

A pair of fixed contacts that are provided on the case body and constitute a two-pole main circuit, a pair of movable contacts that come into contact with and separate from them, a crossbar that connects these pair of movable contacts, and a crossbar that connects the pair of movable contacts; a trip mechanism for detecting overcurrent, and a trip mechanism disposed on one pole side of the case body and connected to the cross bar so that when the trip mechanism detects the trip mechanism, the cross bar is rotated to convert the movable contact to a fixed contact. a link mechanism that separates the movable contact from the fixed contact; a position regulating portion provided on the shaft end of the one pole side of the cross bar; and a position regulating portion provided on the case body that causes the cross bar to separate the movable contact from the fixed contact. A circuit breaker comprising a stopper that comes into contact with the position regulating part when rotated to the desired position.
