Claims

[Scope of utility model registration request]

In a circuit breaker consisting of a conductor and a contact fixed to the conductor, having a pair of movable and fixed electric contacts that open and close each other, and an arc extinguishing plate that extinguishes an arc generated between the two contacts. , the conductors of the movable and fixed electric contacts are each bent into an L-shape so that the center axis of the contact fixing part is perpendicular to the surface of the contact, and the conductor of the movable electric contact is A circuit breaker characterized in that a bent portion is formed to form a current path in the opposite direction to the fixed portion, and the arc-extinguishing plate is formed to extend to both sides of the bent portion of the conductor.
