Various coil types cover a control range from 24 V AC to 240 V AC. NFC contactor relays can be equipped with standard NF accessories. Flexibly interchangeable coil connection terminals allow connection from above, from below, or from above and below. Other accessories such as suppressor elements, etc., complete the range.
