Claims

[Scope of utility model registration request]

At least one pair of fixed and movable electrical contacts, each consisting of a conductor and a contact fixed thereto, that open and close within the container; and an arc-extinguishing plate that extinguishes an arc generated when the electrical contacts open and close. and an arc runner fixed to the tip of the fixed conductor of the pair of contact conductors, the tip of the arc runner being positioned close to the operating locus of the tip of the movable conductor and protruding from the contact surface of the fixed contact. A circuit breaker characterized by extending to
