Claims

[Scope of utility model registration request]

A winding frame having a gate-shaped locking piece support on the end face of one side of the flange and grooves facing each other and opening on two opposite sides of the other side of the flange, around which a coil through which a current flows is wound;
an L-shaped yoke having one leg piece press-fitted into the opposing groove of the other side collar of the winding frame and having a through hole coaxial with the winding frame; a dart pot that is inserted into the through hole and has a flange on the contact end side; a locking piece that is inserted into a locking piece support of one side of the flange of the winding frame and engages with the flange of the darts pot; and the other side leg of the yoke. An overcurrent tripping device for a circuit breaker, comprising a movable iron piece that is swingably supported at one end and that is attracted to the terminal end and performs a tripping operation in accordance with the electric current of the coil.
