Claims

[Scope of utility model registration request]

contact device, opening/closing mechanism, overcurrent tripping device,
In a circuit breaker in which a current transformer and the like for operating the tripping device are housed inside a molded casing, the circuit breaker is juxtaposed to a holder pivotally supported on a frame of the opening/closing mechanism fixed inside the casing. A plurality of movable contact units are arranged inside the casing so as to pass through the current transformer via elastically supported sliding contact terminals provided at one end of the unit. The contactor is configured such that the contact provided at the other end closes and opens with the contact of the fixed contactor of the contactor device by contacting and energizing the connected conductor and operating the opening/closing mechanism. The contact surface of the sliding contact terminal of the movable contact of the device has an arc shape centered on the movable contact pivoting shaft of the holder, and the sliding contact terminal slides the connecting conductor to conduct contact energization. A circuit breaker characterized in that the contact surface of the shaped contact terminal is planar, and a suitable flexible connecting conductor is provided between the movable contact and the connecting conductor.
