Claims

[Claims for Utility Model Registration] 1. A closed envelope is formed by a mold base made of a molded insulator and a mold cover, and an operation handle protruding from the mold cover to the outside allows 1.
A molded circuit breaker configured to open and close a multi-pole main contact device simultaneously by operating a pair of opening/closing mechanisms, and to collapse the opening/closing mechanism in response to an overcurrent and automatically shut off the circuit breaker, wherein the mold The cover is provided with an accessory storage recess that is integrally formed in a corresponding portion of the electrode chamber that does not accommodate the opening/closing operation mechanism, and an auxiliary switch that outputs a contact signal when the main contactor device is opened or closed, as necessary; Accessories such as an alarm switch that outputs a contact signal in response to the automatic cutoff, or a voltage tripping device that trips the molded circuit breaker in response to an external signal are stored in the accessory storage recess, and the accessories are stored in the accessory storage recess. Wiring characterized in that a groove extending toward the main circuit terminal is provided on the front surface of the mold cover continuous with the storage recess, and a lead conductor of the accessory is arranged in the groove and led out to the main circuit terminal side. circuit breaker. 2. Utility model registration claim No. 2, characterized in that a control circuit terminal is provided in the vicinity of the main circuit terminal at a position avoiding the screw operation space of the main circuit terminal, and a lead conductor of an accessory is connected thereto. The hardwired circuit breaker described in item 1.
