Claims

[Scope of utility model registration request]

A closed circuit state is maintained by engaging the catch of the opening/closing mechanism with the catch receiver of the overcurrent tripping mechanism, and when an overcurrent flows in the main circuit, the catch receiver is removed from the catch and the circuit is activated. The circuit breaker is configured to perform a breaking operation, and is rotatably supported by fitting a notch groove formed from the center of rotation to the outer edge into a pin provided in the circuit breaker main body. An interlocking lever that transmits the shutoff operation of the opening/closing mechanism to an attached device such as a micro switch;
A circuit breaker comprising: a torsion coil spring attached to the pin and having one end engaged with the interlocking lever to prevent the interlocking lever from being removed from the pin and biasing the interlocking lever to rotate.
