Claims

[Scope of utility model registration request]

An electromagnetic coil provided in the main circuit, a yoke provided on the side of the electromagnetic coil, and one end supported rotatably by the yoke with one end biased in a direction away from the electromagnetic coil. It also has an integral stopper part that restricts the amount of rotation in the direction away from the electromagnetic coil by contacting the yoke, and is attracted to the electromagnetic coil side when an overcurrent flows in the main circuit. 1. A circuit breaker comprising a movable iron piece for operating a trip mechanism, characterized in that a coating layer of a non-magnetic material having solid lubricating properties is formed on the movable iron piece or the yoke.
