せるようにした回路しゃ断器。A pair of contacts that open and close, a plurality of arc-extinguishing plates that extinguish the arc generated when the pair of contacts open and close, and a pair of side plates that sandwich the plurality of arc-extinguishing plates. In a circuit breaker equipped with an arc extinguishing chamber, a groove is provided between the fixed portions of each arc extinguishing plate of the pair of side plates to which the plurality of arc extinguishing plates are fixed, and the length of the groove is is made longer than the contact portion between the pair of side plates and each of the plurality of arc-extinguishing plates, thereby increasing the insulation distance between the plurality of arc-extinguishing plates.
