Further information for ABB Auxiliary contactor 100 250V50/60 AC/DC 1SBH136001R2359 - NFZ51/11-23
NFZ51/11 contactor relays are used to switch auxiliary and control circuits, including using the integrated delay/pre-run contacts.
The contactor relays have an electronic coil interface that allows a wide control voltage range and can handle large control voltage fluctuations. They withstand short voltage dips and brownouts (compliance with Semi F47-0706). NFZ contactor relays have built-in overvoltage protection and do not require additional suppression elements.
