1SBH136001R2122

ABB NFZ22E-21 (1SBH136001R2122) is a 4-pole auxiliary contactor / contactor relay with 2 Normally Open and 2 Normally Closed contacts. It is designed for switching auxiliary and control circuits in industrial automation, MCC panels, machine-control systems and PLC-based applications.

Its electronic coil operates over a wide 24–60V AC 50/60Hz or 20–60V DC range. Compared with standard NF relays, the NFZ series is optimized for low holding-coil consumption and PLC interfacing, while integrated surge suppression reduces the need for an external suppressor.
