Claims

[Scope of utility model registration request]

A contact opening/closing mechanism that opens and closes the contacts by operating the handle, etc., a short circuit coil that generates electromagnetic attraction force when a large current such as a short circuit current flows, a drive pin that is attracted by the short circuit coil, and a drive pin attraction. A breaker comprising a latch engagement plate that is released from latch engagement with a contact opening/closing mechanism by operation, and a movable contact that is pressed against a driven drive pin and forcibly opens the contact. A breaker characterized by having a trip button on the surface of the cover that can be operated by directly pressing the button.
