Claims

[Scope of utility model registration request]

at least one pair of fixed and movable electrical contacts that are composed of a conductor and a contact fixed thereto and that operate to open and close;
A plurality of arc extinguishing plates are provided to extinguish the arc by being located on the front side in the running direction of the arc generated between the fixed contact and the movable contact, The tip of each fixed conductor is formed into an abbreviated shape so that its central axis is perpendicular to the surface of each contact, and a blowout coil having a winding diameter that includes the opening/closing range of the contact is placed on the side of the contact. 1. A circuit breaker having one end connected to a fixed electric contact, and the other end connected to an arc runner connected to the vicinity of the contact of the fixed electric contact via an insulator.
