Claims

[Scope of utility model registration request]

A closing jacket is formed by a mold base made of a molded insulator and a mold cover, and a set of opening/closing operation mechanisms are operated by an operating handle protruding from the mold cover to open and close the multi-pole main contact device at the same time. In the molded circuit breaker configured to collapse the opening/closing operation mechanism in response to an overcurrent and automatically shut off the circuit, the molded cover is formed integrally with a corresponding part of the pole chamber that does not accommodate the opening/closing mechanism. An auxiliary switch that outputs a contact signal in response to the opening and closing of the main contactor device, an alarm switch that outputs a contact signal in response to the automatic cutoff, or an external signal can be installed as needed. An accessory such as a voltage tripping device for tripping a molded circuit breaker when applied is stored in the accessory storage recess, and an outer wall of the accessory storage recess has a notch and a mounting leg having a locking part. A circuit breaker for wiring, characterized in that a terminal board having a terminal board is inserted into the notch, the accessory storage recess is covered with a recess lid, and the terminal board is fixed.
