NFZ51/11 contactor relays are used to switch auxiliary and control circuits, including using the integrated delay/pre-run contacts. (1NO/1NC) NFZ contactor relays have an electronic coil interface that allows a wide control voltage range and can handle large control voltage fluctuations. Only four coils cover control voltages between 24...250 V 50/60 Hz or 12...250 V DC. NFZ contactor relays have built-in overvoltage protection and do not require additional suppression elements.
