<p>Power supplied from a battery via a power-supply line is distributed via switching means to load drive lines, connected to loads, respectively. Memory means stores the data of current-breaking time characteristics providing the breaking time which corresponds to the amount of each excessive current and the capacity of each load. When any of the current detection means has detected an excessive current flowing through any of the load drive lines, control means breaks power supplied via the load drive line to the load, by opening the switching means immediately after the corresponding breaking time has elapsed.</p> |
