ABSTRACT:
In an auxiliary power unit for a vehicle which comprises a plug to be connected to a cigarette lighter socket provided on the vehicle, and sockets electrically connected to the plug to provide power sources for electrical devices on the vehicle. An overcurrent protective switch is turned off to interrupt the path of current to the sockets when overcurrent flows through the sockets, and a thermally operated member provided for each socket detects the temperature of the socket. When the temperature thus detected exceeds a predetermined upper limit value, the thermally operated member shunts the path of current from the socket, thereby to cause the overcurrent protective switch to operate.
