Special Features | NFZ..K contactor relays are used for switching auxiliary and control circuits. NFZ contactor relays include an electronic coil interface accepting a wide control voltage Uc min. ... Uc max. Only four coils cover control voltages between 24...250 V 50/60 Hz or 12...250 V DC. NF contactor relays can manage large control voltage variations. One coil can be used for different control voltages used worldwide without any coil change NFZ contactor relays allow direct control by PLC-output ? 24 V DC 500 mA and obtain a reduced holding coil consumption. NFZ contactor relays withstand short voltage dips and voltage sags (SEMI F47-0706 compliance) between 24...250 V 50/60 Hz NFZ contactor relays have built-in surge protection and do not require additional surge suppressors. Only NFZ..-20 contactor relays need to respect the polarity on the coil terminals (A1+ and A2-). NFZ..K include Push-in Spring terminals. Only one push is all you need for extremely fast wiring: faster than ever installation, easier than ever wiring, reliable as ever connections. Poles: 8-pole contactor relays with a non-removable front-mounted auxiliary contact block (mechanically-linked auxiliary contacts compliant with Annex L of IEC 60947-5-1 and including the "Mechanically Linked" symbol on the contactor relay side). |

How to Install the ABB NFZ80EK-20 Contactor Relay
Step-by-step guide to mounting and wiring the NFZ80EK-20 contactor relay.
Estimated time: 15m
Tools needed:
Screwdriver, Wire stripper
Supplies needed:
Mounting rail, Mounting screws, Control wires
- Mount the relay to the DIN rail
Position the NFZ80EK-20 on a standard 35mm DIN rail. Ensure it is fully seated and locked in place.
- Connect the control voltage
Insert the control wire into the Push-in Spring terminal at A1+ (positive) or A2- (negative) based on polarity requirements. Push firmly until the wire is secured.
- Connect the load circuit
Insert load wires into the appropriate poles (1-8) of the NFZ80EK-20. Ensure tight connections by pushing the wires into the Push-in Spring terminals.
- Verify mechanical linkage
Confirm the auxiliary contact block is non-removable and mechanically-linked per IEC 60947-5-1. Check for the 'Mechanically Linked' symbol on the relay.
- Test operation
Apply control voltage and verify the relay switches the load circuit correctly. Check for proper operation under expected voltage conditions.
