Abstract
Fuses and a subassembly component for fuses. The fuse includes an insulating housing, a short circuit fusible element, and an arc barrier-forming body. The arc barrier-forming body is fitted around, and intimately surrounds a portion of the short-circuit fusible element. The arc barrier-forming body is formed from a silicone rubber sealant which is free flowing at room temperature but upon exposure to air increases in viscosity until it essentially becomes a solid. The arc barrier-forming body provides protection against 'burn-back' within the fuse.
