Claims

[Scope of utility model registration request]

It consists of a conductor and a contact fixed to the conductor, and is used to extinguish the arc that occurs between the contacts when the electrical contact opens and closes within the container. a plurality of arc-extinguishing plates disposed in the container, and a substantially arc-extinguishing plate having a conductor end side of one of the pair of electric contacts opened toward the main surface side of the conductor. It is formed into a U-shape, and the extending part of the vertical piece on the load side of the almost U-shaped tip extends toward the power supply side as a contact fixing piece, and the contact fixing piece has a tip extending from this. A circuit breaker, wherein the tip portion is inclined downward with respect to a contact fixing surface of the contact fixing piece.
