ABSTRACT:
A wire-protecting apparatus for automobiles in which at least one power-supplying lead for supplying an electric power to a load has at least one PTC element inserted in series with the power-supplying lead. The PTC element exhibits a high resistance at temperatures higher than a predetermined value when an overcurrent greater than a predetermined value flows through the load, thereby substantially shutting off the electric power to the load.
