  • Patent number: 6903649
    Abstract: A fuse that includes an arc energy reducing coating to reduce arc energy during a short-circuit and/or a full voltage overload current interrupt is described. The fuse includes end conductor elements, and at least one fuse element secured between and making electrical contact with the end conductor elements. An elongate fuse housing, having a passageway extending longitudinally through the housing, extends between the end conductor elements. The fuse element extends through the housing passageway. An arc energy reducing coating at least partially coats each end portion of the fuse element.

  • Patent number: 6590490
    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.
