ABSTRACT:
The current path of an electric indicating or striker pin fuse, and more particularly its fusible element, includes a point of maximum resistance where fusion of the latter must take place. That predetermined point is arranged in such a way that the pulverulent arc-quenching filler does not impair the proper operation of the indicating or striker pin device.
