Claims

[Scope of utility model registration request]

A fixed contact attached to a stator, a mover having a movable contact at one end opposite to the fixed contact, and an arc generated between the two contacts when the movable contact is separated from the fixed contact into an arc extinguishing chamber. What is claimed is: 1. A circuit breaker comprising: an arc traveling plate that guides the arc traveling plate, the fixed contact and the movable contact having a triangular shape, and one vertex of the triangular shape facing toward the arc traveling plate.
