NF contactor relays are designed for efficient switching of auxiliary and control circuits. Equipped with an advanced electronic coil interface, they support a wide control voltage range—from 24 to 500 V AC (50/60 Hz) and 20 to 500 V DC—using just four coil variants. This allows for global application without the need to change coils, even in cases of large voltage fluctuations. The relays feature built-in surge protection, eliminating the need for additional suppressors and ensuring enhanced durability and reliability. Each unit comes with four poles and mechanically linked auxiliary contacts, compliant with Annex L of IEC 60947-5-1, and clearly marked with the “Mechanically Linked” symbol. Designed for both AC and DC control circuits, NF contactor relays are also compatible with a wide range of accessories, offering flexibility and adaptability for various control panel configurations.
