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. comprising a movable arm that is supported and performs a tripping operation, and a spring member stretched between the movable contact and the case,
The circuit breaker is characterized in that the spring member is provided so as to apply a spring force in the closing direction when the movable contact is closed, and to apply a spring force in the opening direction when the movable contact is opened.
