The 4-pole NF auxiliary contactors are used to switch auxiliary and control circuits (positively guided contacts available). They have an electronic coil interface that enables a wide control voltage range and can handle large control voltage fluctuations. NF auxiliary contactors have built-in overvoltage protection and do not require additional suppression elements.
