ABSTRACT:
A spiral wound fuse includes an elongated housing, a supporting substrate formed of an electrically non-conducting, resiliently deformable, and flexible material, disposed in the housing, a fusible conductor wound around the supporting substrate and end caps mounted to the housing and connected to the conductor at the first and second ends of the supporting substrate. The fusible conductor may be impressed into the resiliently deformable substrate to form ridges of material between adjacent windings of the conductor. The ridges physically separate the windings and help to prevent arcing or bridging when the conductor melts to interrupt the circuit.
