ABB NF22EK-11 Contactor Relay

NF22EK-11 is a four-pole ABB auxiliary contactor relay designed for switching auxiliary and control circuits in panel installations and motor-control applications. It offers two normally open and two normally closed auxiliary contacts (2S + 2Ö) for signaling and logic functions, and its coil accepts 24–60 V AC (50/60 Hz) or 20–60 V DC, enabling AC/DC operation across a wide range of control circuits. The device is rated for an operational current of 3 A at 400 V, making it suitable for low-current auxiliary switching rather than main power switching. Wiring uses push-in spring terminals, and the unit can be mounted on a DIN rail or with screws to suit common control-panel layouts. For electrical insulation, it supports up to 690 V IEC (and up to 600 V UL), aligning with typical ABB NF-series specifications, while maintaining a compact four-pole form factor ideal for space-constrained installations. Typical uses include signaling, interlocking, and control-logic tasks in conjunction with primary contactors within industrial automation and motor-control panels.
