ABB NF31E-12 (1SBH137001R1231) is a 4-pole contactor relay featuring 3 Normally Open and 1 Normally Closed mechanically linked auxiliary contacts. It is designed for switching auxiliary and control circuits in industrial automation, MCC panels, electrical control panels and machine-control applications.

The NF31E-12 incorporates ABB's electronic coil interface, allowing one relay to operate over a wide 48–130 V AC 50/60 Hz and 48–130 V DC control-voltage range. ABB NF contactor relays also feature built-in surge suppression, reducing the need for additional external surge suppressors.
