Electric fuse is a safety device which is used to protect devices from overflow of current through them. It is usually made of metals with low resistivity and low melting point like copper or an alloy of lead and tin and is connected in series with domestic electric circuits. When excess current flows through the circuit, the circuit gets overheated. The heat produced exceeds the low melting point of the fuse material and thus, melts it off disconnecting the circuit.
