Claims

[Scope of utility model registration request]

A breaker case, a mechanism frame fixed to the bottom wall of the breaker case by two external operation mounting screws and supporting a contact opening/closing mechanism, etc., and a mechanism frame fixed to the bottom wall of the breaker case. In a circuit or disconnector having two mounting holes provided in the mechanism frame and into which the respective mounting screws are respectively inserted, and two screw holes provided in the mechanism frame and into which the respective mounting screws are respectively screwed. , the mounting hole into which the mounting screw to be tightened first is inserted is formed into an elongated oval along the line connecting both mounting holes, and the diameter of the short side of this ellipse is the outer diameter of the mounting screw. A stopper is provided on the breaker case to prevent rotation of the mechanism frame that occurs when the mounting screws on the oval side are tightened, and the mechanism frame positioned by the stopper is fixed to the remaining mounting screws. A circuit disconnector characterized by being fixed with screws.
