Overview

The ABB NFB22ERT-14 contactor relay (SKU: NFB22ERT-14) is a compact, high-reliability device designed for auxiliary and control circuit switching in railway rolling stock. Built by ABB Electrification, this relay meets the latest railway standards, including IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2, and EN 50155, ensuring compatibility with modern train systems operating in tunnels or underground environments. Its reduced dimensions allow for side-by-side mounting, saving up to 15% panel width without spacing, which is critical for space-constrained installations in passenger or driver cabins. The NFB22ERT-14 operates reliably across an extreme temperature range from -40 °C to +70 °C, making it suitable for harsh operating conditions. It meets the highest fire and smoke behavior standards per EN 45545-2 (HL2, HL3 hazard levels) in group mounting, ensuring passenger safety. Energy efficiency is a key feature, with a 68% reduction in coil energy consumption compared to conventional relays, contributing to lower train energy usage. The electronic coil interface accepts sinusoidal AC 50/60 Hz control supplies within a 250-500V range, providing flexibility in power supply configurations. With a rated operational current of 25 A at ≤40 °C and a general use rating of 600V AC, this relay is optimized for auxiliary and control circuit applications. It withstands shocks and vibrations per IEC 61373 category 1, class B, ensuring durability in high-vibration environments like rail transit. The NFB22ERT-14 supports mechanical durability of 20 million operating cycles with a maximum switching frequency of 6000 cycles/h, making it a long-lasting solution for demanding railway applications. Terminals are screw-type with cable clamps, accommodating rigid solid/stranded wires (1-2.5 mm²) and flexible wires with or without ferrules (0.75-2.5 mm²). All terminals are rated IP20 for basic protection. Manufactured in the US, this relay is a reliable choice for new installations or retrofits in railway rolling stock.
