摘要： To provide a circuit breaker that is capable of appropriately moving an arc, which is generated between contact points, toward an arc-extinguishing device, even in a relatively small current region, without enlarging equipment having the circuit breaker. The circuit breaker includes, in each of poles, a pair of front/rear fixed contacts (2, 3) disposed facing each other, a movable contact (4) formed as a bridge between the fixed contacts (2, 3), and a pair of front/rear magnetic drive yokes (10) made from permanent magnets and disposed so as to hold side surface parts on both ends of the movable contact (4) therebetween. In a closed state, the movable contact (4) closes a current feed path of each pole by being pressed against the fixed contacts (2, 3) by a contact spring (5). In an open state, the movable contact (4) opens the current feed paths by being pressed back toward the contact spring (5) by an opening/closing mechanism to separate from the fixed contacts (2, 3).
