Claims

[Scope of utility model registration request]

A circuit breaker comprising a fixed contact, a movable contact provided opposite to the fixed contact, and an arc extinguisher that drives an arc generated between the fixed and movable contacts in a predetermined direction. In the container, a grid plate made of a thin magnetic plate and having a V-shaped groove and a thin insulating plate are formed into a rectangular shape, and a plurality of slit-shaped holes into which the grid plates are inserted are provided in parallel to each other on the sides. The arc extinguishing device may include an insulating support plate, and a plurality of grid plates are inserted and supported in parallel to each other into holes in the insulating support plate arranged on both sides of the grid plate. A circuit breaker characterized by:
