An electromagnetic overcurrent tripping device comprising a leakage iron piece for magnetic flux bypass, which has a U-shaped groove interposed between the upper collar and the armature and is fixed to the inner wall of the other leg of the yoke. In this step, the leaking iron piece is guided into a groove provided in the upper flange of the winding frame and pressed against a plurality of protrusions provided on the inner wall of the other leg of the yoke or fitted between the protrusions. An electromagnetic overcurrent tripping device characterized by being fixed. (2) In the electromagnetic overcurrent tripping device described in claim 1 of the utility model registration, the leaking iron piece is guided to the groove provided in the upper flange of the winding frame, and the leaking iron piece is guided to the inner wall of the other side leg piece of the yoke. An electromagnetic overcurrent tripping device characterized by being fixed by pressure welding of a plurality of protrusions on the opposite side.
