Claims

[Scope of utility model registration request]

A pair of movable contacts and a fixed contact are each provided with a contact at one end, and the other end of the movable contact is rotatably supported at one end, and the other end is supported by a force. A movable arm rotatably supported by the case and tripped by a trip mechanism, and a lever having one end rotatably supported by the movable contact and the other end engaged to interlock with the trip mechanism. 1. A circuit breaker, characterized in that the lever is provided with a claw that opens the movable contact when the lever moves.
