Claims

[Scope of utility model registration request]

In a circuit breaker in which a support frame having side plates on both left and right sides is attached to a case, and an opening/closing mechanism for opening and closing a movable contact is supported on this support frame, a part of the left and right side plates of the support frame is attached to the outside in a tongue shape. A circuit interrupter characterized in that the mounting piece is cut and bent to form an inverted V-shaped mounting piece, and a stepped portion is provided on the opposing surface of the case to engage with the mounting piece of a support frame pushed into the case from above. Device for mounting the opening/closing mechanism support frame.
