1SBH136001R2131 nfz31e-21 24-60v 50/60hz 20-60v -dc ABB Contactor relay

Why Choose the ABB NFZ31E-21?

The ABB NFZ31E-21 is a robust and versatile 4-pole NF contactor relay designed for switching auxiliary and control circuits in demanding industrial environments. Its wide control voltage range, compact design, and compliance with industry standards make it an ideal choice for panel builders, electricians, and maintenance engineers. The NFZ31E-21 simplifies control circuit design by accepting a wide control voltage range (24-250V AC/DC), eliminating the need for multiple coil versions. It features direct PLC control compatibility (≥ 24V DC 500mA) and reduced holding coil consumption for enhanced energy efficiency. Built-in surge protection and compliance with SEMI F47-0706 ensure reliable operation even under fluctuating voltage conditions.
