Overview

The ABB NFZ44EK-22 is an 8-pole contactor relay designed for switching auxiliary and control circuits in industrial automation, building management, and process control applications. This model features a compact design with a weight of 0.360 kg per unit, optimized for space-constrained installations while maintaining robust performance. The NFZ44EK-22 accepts a control voltage range of 48 to 130V AC (50/60 Hz) or 48 to 130V DC, eliminating the need for voltage-specific coil replacements across global installations. The electronic coil interface ensures compatibility with PLC outputs ≥24V DC at 500mA, reducing holding coil consumption during continuous operation. Built-in surge protection eliminates the requirement for external surge suppressors, enhancing system reliability and reducing component count. The front-mounted auxiliary contact block is non-removable and includes mechanically-linked contacts compliant with Annex L of IEC 60947-5-1, ensuring fail-safe operation in critical control circuits. Push-in spring terminals enable tool-free wiring with a single push, reducing installation time by up to 50% compared to traditional screw terminals while maintaining vibration-resistant connections. The NFZ..K series is manufactured by ABB Electrification in the US, with UNSPSC classification 39121529, making it suitable for UL and cUL certified installations. Typical applications include motor control centers, HVAC systems, conveyor automation, and industrial machinery requiring reliable auxiliary switching. The relay's design withstands short voltage dips and sags per SEMI F47-0706 standards within its specified voltage range, ensuring stable operation during grid disturbances. With a front-mounted mounting type and 8 poles, the NFZ44EK-22 provides a versatile solution for complex control circuit architectures while minimizing panel space requirements.
