    The melting point of a ruse wire is low.
    Reason:-
    A fuse works by opening an electrical circuit when the current becomes too high. Current increases with the temperature of wire. If the current is too high the fuse melts, opening the circuit and halting additional current flow. The current at which fuse open is controlled by the composition of the wire. Low current is low melting point of the wire. So the melting point is not higher than of normal wire.
