Electric fuse is a protective device which protects electrical equipment in the circuit by breaking the circuit when there is a short circuit. It is made up of the alloy of tin and lead. It has low melting point and high resistance.

A fuse is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, interrupting the circuit that it connects. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for excessive current. Fuses can be used as alternatives to circuit breakers. A fuse interrupts an excessive current so that further damage by overheating or fire is prevented.
