ABSTRACT:
A fuse element having a substantially planar strip formed of an electrically conductive metal having a central portion and opposite end portions. The central portion is provided with a plurality of diamond-shaped perforations. The perforations form a plurality of branches that define a plurality of elongated, narrowed electrical pathways across the central portion. The joints where the branches meet form the weak spots for the fuse element. The central portion of the fuse element is encased in a material that is electrically non-conducting and heat conducting. The material, a ceramic, for example, is injection molded in and around the perforations to substantially completely encase the central portion of the fuse element.
