The ABB NFZ contactor relay is used for switching auxiliary and control circuits. NFZ contactor relay include an electronic coil interface accepting a wide control voltage Uc min. to Uc max. It has only four coils cover control voltages between 24 to 250 V 50/60 Hz or 12 to 250 V DC. It can manage large control voltage variations.
One coil can be used for different control voltages It has built-in surge protection and do not require additional surge suppressors 8-pole contactor relay
