The NF71EK-14 is a 690 V IEC or 600 UL 8-pole contactor relay with Push-in Spring terminals, used for switching auxiliary and control circuits.
Only one push is all you need for extremely fast wiring: faster than ever installation, easier than ever wiring, reliable as ever connections.
Thanks to the AF technology, the contactor relay has a wide control voltage range (250-500 V 50/60 Hz and DC), managing large control voltage variations, reducing panel energy consumptions and ensuring distinct operations in unstable networks. Furthermore, surge protection is built-in, offering a compact solution. NF contactor relays have a block type design, can be easily extended with add-on auxiliary contact blocks and an additional wide range of accessories.
These contactor relays include mechanically-linked auxiliary contacts compliant with Annex L of IEC 60947-5-1 and are side-marked with the "Mechanically Linked" symbol.
