The fuse breaks the circuit if a fault in an appliance causes too much current flow. This protects the wiring and theappliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wireheats up until it melts and breaks the circuit.

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrentprotection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and it must be replaced or rewired,

Fuses have been used as essential safety devices from the early days of electrical engineering. Today there are thousands of different fuse designs which have specific current and voltage ratings, breaking capacity and response times, depending on the application. The time and current operating characteristics of fuses are chosen to provide adequate protection without needless interruption. Wiring regulations usually define a maximum fuse current rating for particular circuits. Short circuits, overloading, mismatched loads, or device failure are the prime reasons for fuse operation.
A fuse is an automatic means of removing power from a faulty system; often abbreviated to ADS (Automatic Disconnection of Supply).
