Claims

[Scope of utility model registration request]

(1) In a circuit breaker that is driven by an opening/closing mechanism and has a movable contact that moves toward and away from a fixed contact, an electromagnetic device that is activated by a predetermined overcurrent and has a movable element that presses the movable contact; and a support member that supports the movable contact movably in the operating direction of the movable core,
A circuit breaker characterized in that the movable contactor rotates about a contact portion of a surface contactor as a fulcrum when the electromagnetic device operates.

(2) the support member is provided near the electromagnetic device, and a fixed member movably supports the rear end of the movable contact;
The circuit breaker according to claim 1, further comprising an actuating member that always urges the movable contact toward the movable iron core.

(3) The circuit breaker according to claim 2, wherein the operating member is a compression spring.

(4) The circuit breaker according to claim 1 or 2, wherein the support member includes an interlocking plate operated by the opening/closing mechanism.
