The 4-pole NFZ contact relays are used for switching auxiliary and control circuits. They feature an electronic coil interface that can accommodate a very wide control voltage range. This means they can handle significant fluctuations in control voltage. They require a very low holding power of only 1.7 W. NFZ auxiliary contactors can withstand short voltage dips and drops. They have integrated surge protection and do not require additional suppressors. Furthermore, a wide range of accessories is available.
