Claims

[Claim for Utility Model Registration] Magnetic attraction is generated by a large current such as a short-circuit current flowing through a coil, and this magnetic attraction causes a movable iron core to be driven to trip a trip mechanism consisting of a trip lever, latch lever, etc. It has a tripping part that operates, and the operation of this tripping part forcibly opens the fixed contact and the movable contact, and the arc accompanying the opening of the fixed contact and the movable contact is passed through the arc traveling plate. In a breaker configured to extinguish an arc using an arc extinguishing device, one of the tripping sections of the plurality of tripping sections is disposed on the base and is movable. A yoke rotatably supports a contact with fixed points, and one end of the yoke is attached to an arc traveling plate that is integrally extended in a slender shape, and is excited by an external signal and whose cross-sectional shape is an arc traveling plate. a coil block approximately corresponding to the coil block, an iron core inserted through the coil block and fixed to the arc travel plate of the yoke, a hinge fixed to the other end of the yoke and having elasticity, and a hinge with a misaligned end. It consists of a movable iron piece that is fixed and whose upper end engages with the trip lever.
A structure of a breaker characterized in that a movable iron piece is attracted to an iron core by excitation of a double block, thereby driving a trip leg and causing a trip operation.
