Claims

[Scope of utility model registration request]

(1) Equipped with an electromagnet that is excited by a current that exceeds a preset overcurrent and a movable core that is activated by the excitation of this electromagnet. A circuit breaker in which a contact element separates from a fixed contact element includes a tube or tunnel-shaped cavity, and is inserted into the cavity and moves from one end side of the cavity to the other end side by the operation of the movable iron core, A circuit breaker characterized in that the movable contact is equipped with a transmission body that acts in the opening direction of the movable contact.

(2) The circuit breaker according to claim 1, wherein the transmission body is configured to act on the movable contact after the trip bar is released from the fredle.
