Claims

[Scope of utility model registration request]

(1) - A circuit breaker with an operating arm that is always deflected in one direction by a spring around an axis, and a first solenoid electromagnet whose fixed electromagnetic part is fixed to a base and has a movable iron core;
a connecting lever connected between the shaft of the movable iron core and a shaft provided on the operating arm of the circuit breaker; and a bird's beak-shaped portion at the tip of the extension of the operating arm when the circuit breaker is closed. a tripping metal fitting that engages and is built in and always applies a biasing force in a counterclockwise direction, and a tripping metal fitting that applies a biasing force in a clockwise direction, and the first solenoid when the movable iron core is attracted. a second tripping electromagnet for disengaging the claw metal fitting from the tripping metal fitting and the bird's beak-shaped portion of the operating arm; A circuit interrupter characterized by comprising:

(2) The circuit breaker device according to claim 1, in which the second tripping electromagnet is constantly excited to act as a stopper for the movable iron core in the opening direction, and is also used as a no-voltage and under-voltage coil.

(3) The movable iron core is implanted with an insulating rod, and as the movable iron core moves, the hinge lever of the microswitch is pressed;
A circuit breaker device according to claim 1, which opens a microswitch.
