Claims

[Scope of utility model registration request]

In a circuit breaker having at least one pair of electrical contacts that are configured by a conductor and a contact fixed thereto and operate to open and close, the contact fixing portion of the electrical contact is arranged so that its central axis is relative to the surface of the contact, The cross-sectional area of the fixed end of the contact is set to be approximately the same as the surface area of the intersection, and a pair of magnetic flux plates facing each other are arranged to sandwich the contact from both sides. A circuit breaker characterized by having a permanent magnetic flux installed in it.
