ABSTRACT:
A plug-in fuse200comprises a body201with side indented portions203which allow secure gripping by the thumb and finger of a hand. The side indented portions define upper and lower extended portions319, 321allowing insertion and retraction forces to be exerted on the fuse. The improved body shape allows quick and easy insertion of the fuse in high-density fuse holders. A thermally-degradable material323in close proximity to the burnout portion of the fuse element provides visual and/or tactile indication of fuse condition.
