Claims

[Scope of utility model registration request]

A pair of movable and fixed contacts consisting of a conductor and a contact fixed to the conductor, which open and close with each other, are bent into a U-shape so that the center axis of the fixed contact part of the conductor is perpendicular to the surface of the contact. At the same time, the conductor of the movable contact is further provided with a bent part that forms a current path in the opposite direction to the above-mentioned contact fixed part, and a magnetic flux plate made of a magnetic material having a substantially U-shape is placed on both sides of the bent part. A circuit breaker characterized in that the pieces face each other across at least both sides of the bent part, and are arranged so that the opening between the tips of both pieces is located on the contact fixing part side.
