Abstract
A fuse comprises a housing assembly, at least one primary fuse link extending within the housing assembly, at least a pair of fuse terminals connected to the primary fuse link and extending from the housing assembly, and a retractable handle assembly coupled to the housing assembly. The handle assists in removal of the fuse from a switch housing assembly.
Claims22
A fuse comprising:
- a fuse housing;
- at least one primary fuse link extending within and enclosed by said fuse housing;
- at least a pair of fuse terminals mechanically and electrically connected to said at least one primary fuse link, said pair of fuse terminals extending from said fuse housing;
- and
- a retractable handle assembly coupled to said fuse housing, said handle assembly comprising a base spacer element and a handle element extending into said base spacer element, said handle element selectively positionable relative to said base spacer element, said handle element comprising a stop flange, said base spacer element comprising at least one stop projection therein, said stop flange contacting said stop projection when said handle is in an open position.

A fuse comprising:
- a housing assembly;
- a first primary fuse link and a second primary fuse link extending within said housing assembly, each of said first primary fuse link and said second primary fuse link coupled to a pair of fuse terminals extending from said housing assembly, said first primary fuse link and said second primary fuse link extending in parallel between each respective pair of fuse terminals;
- and
- a handle assembly coupled to said housing assembly, said handle assembly comprising a handle element and a base element coupled to said housing assembly, said handle element selectively positionable relative to said base element between a retracted position wherein said handle element is substantially flush with a top surface of said housing assembly and an extended position wherein said handle element is separated from said top surface of said housing assembly.
