Fuses - Electric

A fuse provides over-current protection. Fuses have a metal wire or strip that melts when too much current flows. Fuses prevent excessive current so that further damage by overheating or fire is prevented. Fuses are selected to allow passage of normal current plus a marginal percentage and to allow excessive current only for short periods. Fuses are manufactured in a wide range of current and voltage ratings. Fuses are widely used to protect wiring systems and electrical equipment. Self-resetting fuses are useful in aerospace or nuclear applications where fuse replacement is impossible.
