Important

Auxiliary contacts NC and COM are normally closed .

When the contacts are open and the coil voltage is “0 V”, the part is stuck.

Coil (+) and coil (−) are suppressed with a surge protection device.

Auxiliary contact

Example circuit to realize stuck detection:

The LED will be ON when the contactor is OFF.

In case the contactor is stuck, the Aux COM and Aux NC contacts will remain open, hence the circuit

is open, and the LED will be off, indicating the malfunction.
