(1) A movable electrical contact and a fixed electrical contact each having a conductor and a contact fixed to the conductor so that the direction of electricity flowing through each conductor in the closed state is the same and is approximately straight. In a circuit breaker in which a fixed contact is fixed to the center of the fixed conductor in the width direction of the fixed electric contact, the rear end edge of the fixed contact is fixed to the fixed conductor at the center of the width direction of the fixed conductor. A through groove is provided which extends further rearward and divides the current flowing through the fixed conductor to both ends in the width direction, and within this through groove extends rearward from the rear end side of the fixed contact,
A circuit characterized in that an arc running path is provided that does not normally serve as an electric path, and the width of the through groove is larger than the width of the contact, and the width of the arc running path is smaller than the width of the contact. Breaker.
