Claims

[Scope of utility model registration request]

(1) A movable electric contactor and a fixed electric contactor having a conductor and a contact fixed to the conductor, in which the direction of electricity flowing through each conductor in the closed state is the same and is approximately linear. In the circuit breaker, a fixed contact is fixed to the fixed conductor in the widthwise center of the fixed electric contact, and the fixed contact is fixed to the fixed conductor in the widthwise center. A through groove is provided that extends rearward from the rear edge of the fixed conductor and divides the current flowing through the fixed conductor to both ends in the width direction. 1. A circuit breaker, characterized in that an arc traveling path is provided, and the upper surface of said arc traveling path is inclined with respect to a fixed conductor so as to descend as it moves away from said contact point.

(2) The circuit breaker according to claim 1, which is a registered utility model, wherein the surface of the circuit breaker except for the arc travel path and the electrical contact surfaces of the contacts is covered with a pressure reflector made of an insulator or a high-resistance material.
