Design and fabrication of printed fuse

A power fuse is provided to protect an electrical load subject to cyclic transient load current events in a direct current electrical power system. The power fuse includes at least one fuse element assembly that includes an elongated planar substrate, a plurality of fuse weak points, and a conductor. Weak spots form on the substrate and are spaced longitudinally from each other on the substrate. The conductor is supplied separately from the substrate and weak points. The conductor includes an elongated solid strip of metal that has no weak point openings stamped into it and therefore prevents thermomechanical fatigue stress on the conductor when subjected to cyclic transient load current events. The elongated solid strip of metal includes coplanar connector sections that are mounted at respective weak points and sections that extend obliquely bent out of the plane of the connector sections to extend above the substrate.
