ABB NF Control Relays

NF control relays are the four-pole contactor relays used throughout ABB control circuits for interlocking, signalling and auxiliary switching. Like the AF contactors they share a range with, the NFZ and NFC versions use wide-band electronic coils, so a single part number covers a broad control-voltage range.

What to check before ordering

• Confirm the contact configuration — 4NO, 3NO+1NC and 2NO+2NC are different part numbers.
• Check the coil band against your control voltage; AC and DC bands are stated on the reference.
• Control relays are not motor contactors: do not use them to switch a motor branch.
• Additional auxiliary blocks can be added on the front where more contacts are needed.

Frequently asked questions

What is the difference between NF and NFZ?

They are variants within the same control-relay family, differing mainly in coil technology and control interface — NFZ uses the electronic wide-band coil with low holding power, suitable for direct PLC-output control.

Can I drive an NF relay directly from a PLC output?

The electronic-coil versions draw very little holding current, which makes direct PLC-output control practical. Check the output's rated current against the coil's inrush, and fit a surge suppressor.

Are more contacts available?

Yes — front-mounted auxiliary contact blocks add contacts to the base relay.
