Abstract

The electric motor is driven by a microswitch. This microswitch actuates a delayed action microrelay which itself actuates a power relay which closes the supply circuit to the motor. In the case of a three phase star connected motor supplied at a voltage greater than 260 volts the supply circuit contacts are inserted in the star connection of the motor. The motor protection circuit has at least a thermal contact fitted inside the motor which actuates a relay which opens the supply circuit when the motor is overheated.
