Claims

[Scope of utility model registration request]

(1) In a circuit breaker equipped with a handle that can be operated from outside the housing and an opening/closing mechanism operated by the handle, a movable element to which a movable contact operated by the opening/closing mechanism is fixed, and a movable element facing the movable contact. A fixed terminal having a fixed contact fixed to one end and a screw for connecting an external conductor to the other end;
It is divided into two prongs, and the L-shaped bent ends of the two prongs are fixed to the end face of the terminal on the fixed contact side so that the fixed contact is positioned in the forked opening, and the terminal forms an approximately U shape. A circuit breaker characterized by being equipped with an arc runner that forms a letter-shaped conductor part.

(2) The circuit breaker according to claim 1, which is a registered utility model, characterized in that a narrow groove is provided in the longitudinal force direction of the arc runner from the forked space of the arc runner.

(3) The circuit breaker according to claim 1 or 2, wherein the upper surface of the arc runner is installed slightly higher than the upper surface of the fixed contact.

(4) The circuit breaker according to any one of claims 1 to 3, wherein the tip of the L-shaped bent portion of the arc runner is fixed to the terminal with a screw.
