NF /AF contactor include an electronic coil interface accepting a
wide control voltage Uc min. ... Uc max. only four coils cover
control voltages between 24...500 V 50/60 Hz or 20...500 V DC
NF / AF contactor can manage large control voltage variations. One
coil (e.g. 100...250 V 50/60 Hz - DC) can be used for different
control voltages used worldwide without any coil change.
NF...Z / AF...Z contactor equipped with a Z coil type allow direct
control by 24 V DC 500 mA PLC-output and obtain a reduced holding
coil consumption.
NF / AF contactor have built-in surge protection and do not require
additional surge suppressors.
