Claims

[Scope of utility model registration request]

It is equipped with a pair of contacts that open and close, and an arc extinguishing chamber in which a plurality of arc extinguishing plates are installed between a pair of side plates to extinguish the arc generated when the contacts open and close. In the circuit breaker, an arc-extinguishing base material having a large number of holes and an arc-extinguishing base material having no holes are superposed so as to be in contact with each other to form one arc-extinguishing plate,
A circuit breaker characterized in that a plurality of arc extinguishing plates are installed at a predetermined interval between the pair of side plates.
