The 8-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, meaning that even large control voltage fluctuations can be handled.
They have built-in overvoltage protection and do not require any additional suppressors. A wide range of accessories is also available. For types with coil code -20, the connection polarity (A1+ / A2-) must be observed.
