Abstract
In an exemplary embodiment of the invention, a fuse element for a time delay fuse includes a conductive fuse element member, a fuse link formed within the member, and a heat sink coupled to the member. The heat sink draws heat from the fuse element member and prevents the fuse link from opening for an increased amount of time during high current overload conditions.
