1SBH136001R2131

ABB NFZ31E-21 (1SBH136001R2131) is a 4-pole auxiliary contactor / contactor relay with 3 Normally Open and 1 Normally Closed contacts, intended for switching auxiliary and control circuits. The NFZ electronic coil supports 24–60V AC 50/60Hz or 20–60V DC, provides reduced holding-coil consumption, tolerates short voltage dips, and incorporates built-in surge protection. ABB also specifies that NFZ contactor relays can be directly controlled by a suitable PLC output ≥24V DC / 500mA.
