る配線用遮断器。 A trip device that is activated when an excessive current passes through it, and a trip device that performs a trip operation when the trip device is activated in a set state that accumulates spring force and is configured by attaching a plurality of links and springs to a holding frame. A molded circuit breaker in which a device and a contact device, which is mechanically connected to a trip device and opens a contact inserted into a main circuit in accordance with the tripping operation of the trip device, are housed in a fixed position in a housing. The tripping device includes a coil for detecting excessive current, a yoke disposed to surround the coil, a plunger inserted through the yoke so as to be movable forward and backward, and a return spring for returning the plunger to its home position. The coil is formed in a rectangular sheet metal in a substantially L-shape, with the tip of one leg having a notched groove opened in the side edge of the sheet metal and bent into a substantially L-shape along the other leg, and a yoke. is formed into a substantially S-shape in which three horizontal pieces arranged in parallel are connected together by a vertical piece, and one of the vertical pieces of the yoke is placed in one of the pair of gaps formed between the horizontal pieces of the yoke. A molded circuit breaker consisting of a coil arranged in such a way that a horizontal piece of the coil is interposed between the vertical piece of the coil and the vertical piece of the coil.
