Abstract

A fuse assembly has snubber/indicators which are visible through translucent lenses provided within the fuse cover, for indication and inspection of the fuse operability. The snubbers provide a shearing load upon the fuse filament so as to more positively separate the fuse segments of a ruptured filament, which snubbers may also envelop and insulate the conductor posts and separate the ruptured fuse elements so as to inhibit arcing within the "blown" fuse.
