Normal operation: If the supply voltage is applied to the terminals A1 / A2, the motor contactor is released by means of a potential-free contact and is switched on. One synchronised contact is installed in the device.

In case of error: Due to heating of the resistors (PTC characteristic) within the stator windings, the thermistor motor protection relay is triggered as soon as the limit value has been reached, the contactor drops out.

Establishing normal operation: Only after the resistor has cooled down, the thermistor motor protection relay can be reset to normal operation by means of the reset button.
