Working of Fuse

Working of Fuse Points : Working of Fuse, Material of Fuse, Definition of Fuse Fuse Fuse is a wire of short length or thin strip of material having low melting point and is inserted in an electric circuit as protective device to the flow of an excessive current through the circuit (i.e. current greater than the maximum current allowed to flow through the circuit in normal condition). Material Tin, lead, zinc, and allow of lead and tin, silver copper, aluminum etc. materials can be used for fuse wire. Mostly, lead-tin allow is used for 10-amp current rating fuse. Working of Fuse Under normal working conditions the current flowing through the circuit is within safe limits but when some faults, such as short circuit occurs or when load more than limiting value the fuse wire gets heated up, melts and breaks the circuit. It thus protects a machine or apparatus from being damaged due to excessive current.
