Claims

[Scope of utility model registration request]

A number of grid plates are provided at intervals between the other ends of the first arc running plate having a fixed contact connected to one end and the second arc running plate having a movable contact connected to one end. In an arc extinguishing device for a breaker equipped with parallel arc extinguishing grids, the grid plate of the arc extinguishing grid is removed from the underside of a cover made of an insulating material that covers the upper surface of the base on which the arc travel board is installed. An arc extinguishing device for a breaker characterized by integrally protruding protrusions made of insulating material positioned between them.
