A surge protector includes a thermal fuse, a metal oxide varistor electrically connected in series relation to the thermal fuse, and a detection network electrically connected in parallel relation to the thermal fuse and the metal oxide varistor. A first indicating means indicates whether or not the thermal fuse is in operation and a second indicating means indicates whether or not the metal oxide varistor is in operation.
