Claims

[Scope of utility model registration request]

At least one pair of electrical contacts consisting of a conductor and a contact fixed thereto and operating to open and close within the container; a plurality of arc-extinguishing plates disposed in a substantially U-shape with the tip side of the conductor of one of the pair of electric contacts opening toward the main surface side of the conductor; At the same time, the tip of the load-side vertical piece of this substantially U-shaped tip extends toward the power source side as a contact fixing piece, and the contact fixing piece faces the contact side and extends toward the tip side. A circuit breaker characterized in that an arc runner is fixed to the conductor of one of the electric contacts, and the non-contact side termination of the arc runner is set to be located on the contact side from the non-contact side termination of the arc extinguishing plate. vessel.
