Abstract

The system conceived protects single phase asynchronous electric motors from overload, short circuiting and accidental start-up and is not affected by the vibration produced while pan concrete mixers used in the building industry are in operation. In order to achieve these results we have mounted on a suitable housing, in order: an EEC pin, a valve, a thermal sensor, and a switch having a minimum voltage coil. The thermal sensor has the function of a normally closed switch which is opened by the temperature of the surroundings and the line current which we have preset. Opening of the sensor immediately cuts the voltage to the coil of the switch which trips open immediately interrupting the circuit. <IMAGE>
