The 4-pole AF auxiliary contactors are used for switching auxiliary and control circuits (positively driven contacts). They have an electronic coil interface. This allows a wide control voltage range on both AC and DC voltage. NF auxiliary contactors have built-in surge suppression and therefore do not require additional suppressors (RC element/varistor). Voltage range: 24...60V Voltage type: AC and DC Accessories overview Overview NF-contactor relays
