Overview

The ABB NFZ40EK-20 is a 4-pole contactor relay (SKU: NFZ40EK-20) designed for switching auxiliary and control circuits. This model features an electronic coil interface that accepts a wide control voltage range, specifically Uc min. to Uc max. Only four coils are required to cover control voltages between 24...250 V 50/60 Hz or 12...250 V DC, allowing NFZ contactor relays to manage large control voltage variations. This means one coil can be used for different control voltages utilized worldwide without the need for any coil change. NFZ contactor relays allow direct control by PLC-output ≥ 24 V DC 500 mA and achieve a reduced holding coil consumption. Furthermore, NFZ contactor relays withstand short voltage dips and voltage sags, complying with SEMI F47-0706 standards between 24...250 V 50/60 Hz. Built-in surge protection is integrated into NFZ contactor relays, eliminating the need for additional surge suppressors. It is important to note that only NFZ..-20 contactor relays require adherence to polarity on the coil terminals (A1+ and A2-). The NFZ..K series includes Push-in Spring terminals, enabling extremely fast wiring with just one push, resulting in faster installation, easier wiring, and reliable connections. The NFZ40EK-20 is a 4-pole contactor relay, featuring mechanically-linked auxiliary contacts that are compliant with Annex L of IEC 60947-5-1 and include the "Mechanically Linked" symbol on the contactor relay side. A wide range of accessories is available for this product.
  • 4-pole contactor relay with mechanically-linked auxiliary contacts (IEC 60947-5-1 Annex L compliant)
  • Push-in Spring terminals for tool-free, fast wiring (single push required)
  • Control voltage range: 12–20V DC for low-voltage control systems
  • Compact design (0.310 kg per unit) with direct PLC control compatibility (≥24V DC, 500mA)
  • Manufactured in the US with a full range of accessories available
