1SBH136001R2331

ABB NFZ31E-23 (1SBH136001R2331) is a 4-pole auxiliary contactor / contactor relay with 3 Normally Open and 1 Normally Closed contacts, designed for switching auxiliary and control circuits in industrial electrical and automation systems.

The NFZ series uses an electronic wide-range coil operating from 100–250V AC 50/60Hz or 100–250V DC. It supports direct PLC control with suitable ≥24VDC / 500mA outputs, offers reduced holding-coil consumption, tolerates short voltage dips, and includes built-in surge protection, so an additional surge suppressor is generally not required.
