NFZ33/11 contactor relays are used to switch auxiliary and control circuits, including using the integrated delay/pre-run contacts. 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 withstand short voltage dips and voltage drops (conformity to Semi F47-0706). They have built-in overvoltage protection and therefore do not require additional suppressors.
