Claims

[Scope of utility model registration request]

A pair of movable contacts and a fixed contact each having a contact point at one end, and the other end of the movable contact rotatably supported by one end, and the other end rotatably attached to the case. The arm includes a movable arm that is supported and performs a trip operation, and a locking mechanism that locks the movable contact from closing when the movable contact is opened, and the locking mechanism includes a leaf spring provided on the movable contact. and a locking part formed on the case to lock the locking piece when the movable contact is opened, and the locked state of the locking mechanism is controlled by rotating the movable arm. A circuit breaker characterized in that it is configured to be released.
