1SBH136001R2022

ABB NFZ22E-20 (1SBH136001R2022) is a 4-pole auxiliary contactor / contactor relay with 2 Normally Open and 2 Normally Closed mechanically linked contacts. This particular -20 version uses a 12–20 V DC coil, making it suitable for low-voltage DC control applications. The coil is polarity sensitive, so A1 must be positive and A2 negative.

Typical applications include PLC/control panels, MCC panels, machine automation, electrical interlocking, signalling circuits, status feedback and industrial control systems.
