NFZ contactor relays are designed for switching auxiliary and control circuits with high reliability and versatility. They feature an advanced electronic coil interface that supports a wide range of control voltages—from 24 to 250 V AC (50/60 Hz) and 12 to 250 V DC—allowing just four coils to cover global voltage requirements. This eliminates the need to change coils for different applications and enables the relays to handle significant control voltage fluctuations with ease.
These contactor relays are optimized for direct control by PLC outputs ≥ 24 V DC, 500 mA, and offer reduced coil holding consumption. NFZ relays are compliant with SEMI F47-0706 standards, ensuring they can withstand short voltage dips and sags across the full control voltage range. Integrated surge protection is built in, eliminating the need for external suppressors.
The relays come with 4 poles and include mechanically linked auxiliary contacts in accordance with Annex L of IEC 60947-5-1, visibly marked with the “Mechanically Linked” symbol on the device. NFZ contactor relays are available in both AC and DC operated control circuits, and a wide range of accessories is offered for flexible integration.
