Melting point required for fuse wires is low.

Fuse wires are present in circuit board and connected in series with live wire.

These wires have characteristic property of low melting points and high resistivity.

The properties are for the reasons as - High resistivity aims at inhibiting flow of current, thus causing heating of wire and hence its melting.

Low melting point is taken to melt the wire on increased temperature. This is done to break the circuit, thus halting flow of heavy current to appliance, which might damage it.
