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.
Claims11
A fuse comprising:
- a first and a second end conductor element;
- a fuse wire secured between and making electrical contact with said end conductor elements, said fuse wire comprising a first end portion, a second end portion, and a center portion extending between said first and second end portions;
- an elongate fuse housing comprising an inside surface defining a passageway extending longitudinally from a first end to a second end of said housing, said housing extending between said end conductor elements, said fuse wire extending through said passageway;
- a silicone coating at least partially coating said first and said second end portions of said fuse wire;
- and
- a substantially flat nonconductive bridge comprising a first end portion, a second end portion, and an elongate central portion, said elongate central portion comprising first and second side sections extending between said first and second end portions of said bridge, said first and second side sections defining an elongate opening in said bridge, said fuse wire extending between and coupled to said first and second end portions so that said fuse wire makes electrical contact with said first and second conductor elements, said fuse wire extending through said elongate opening in said bridge.
A fuse comprising:
- a first and a second end conductor element;
- a fuse wire secured between and making electrical contact with said end conductor elements over a nonconductive bridge, said fuse wire comprising a first end portion, a second end portion, and a center portion extending between said first and second end portions;
- said bridge comprising an elongate central portion comprising a central opening therethrough, said fuse wire extending through said opening;
- an elongate fuse housing comprising an inside surface defining a passageway extending longitudinally from a first end to a second end of said housing, said housing extending between said end conductor elements, said fuse wire extending through said passageway;
- and
- an arc energy absorbing silicon coating at least partially coating said first and said second end portions of said fuse wire.
A fuse comprising:
- a first and a second end conductor element;
- a fuse wire secured between and making electrical contact with said end conductor elements, said fuse wire comprising a first end portion, a second end portion, and a center portion extending between said first and second end portions;
- an elongate fuse housing comprising an inside surface defining a passageway extending longitudinally from a first end to a second end of said housing, said housing extending between said end conductor elements, said fuse wire extending through said passageway;
- a nonconductive bridge comprising a central opening therethrough, said fuse wire extending through said opening;
- and
- an arc energy absorbing silicon coating covering a portion of said first and said second end portions of said fuse wire, said center portion free of said coating.
