NF33/11 contactor relays are used to switch auxiliary and control circuits, including using the integrated delay/pre-run contacts. (1NO/1NC)
NF contactor relays have an electronic coil interface that allows a wide control voltage range and can handle large control voltage fluctuations. They have built-in overvoltage protection and do not require additional suppression elements.
