  • at least one power-supplying lead for supplying an electric power to a load;

    at least one PTC element inserted in series with said power-supplying lead, whereby said PTC element exhibits a high resistance at temperatures higher than a predetermined value when an overcurrent greater than a predetermined value flows through said load, thereby substantially shutting off the electric power to the load; and
