<P>PROBLEM TO BE SOLVED: To provide a spring type meltable alloy protective component, which can effectively prevent creep of low melting point alloys caused by compression reaction of a compression spring, thereby guaranteeing the normal operation of the protective component. Ž<P>SOLUTION: The invention is provided with a pair of wire fixing electrodes 2a and 2b, a guiding shaft 3 arranged side by side with the wire fixing electrodes, a movable electrode 2c archedly arranged between the wire fixing electrodes 2a and 2b while being inserted into the guiding shaft 3, wherein the low melting point alloys 5a and 5c are used to joint the front end of each of the wire fixing electrodes 2a and 2b and the movable electrode 2c, and to joint the guiding shaft 3 and the movable electrode 2c; a compression spring 4 is arranged for biasing the movable electrode to be separated from the wire fixing electrodes, due to the melting of the low melting point alloys 5a and 5c, the movable electrode 2c is activated by the compression spring 4 to separate from the wire fixing electrodes 2a and 2b.
