The 4-pole NFZ auxiliary contactors are used to switch auxiliary and control circuits (positively guided contacts available). They have an electronic coil interface that can implement a very wide control voltage. This means that even large control voltage fluctuations can be handled. They require a very low holding power of just 1.7W. NFZ auxiliary contactors can withstand short voltage dips and voltage drops (according to SEMI F47-0706) between 24...250 V 50/60 Hz. They have built-in overvoltage protection and do not require any additional suppressors. A wide range of accessories is also available.
