If current increases beyond specified amperage, fusible metal
melts and the circuit is broken, thus protecting cable and
electrical equipment from burning.

a. When replacing fusible link, be sure to use one with the
specified rating.
b. Blown fusible link is caused by short circuit in the source of
electricity circuit or large amperage circuit, so certain check of
cause and/or repair is necessary.
