AF contactors are AC/DC operated
AF09-AF38 contactors include an electronic coil interface accepting a wide control voltage Ucmin - Ucmax. Only four coils cover control voltages 24 → 500 Vac or 20 → 500 Vdc
AF..Z contactors equipped with a Z coil type allow direct control by 24 Vdc, 500 mA PLC output and obtain a reduced holding coil consumption
AF.Z contactors withstand short dips and voltage interruptions (SEMI F47-0706 compliance)
AF40-AF96 contactors are mainly used for controlling 3-phase motors and power circuits up to 690 V AC and 220 V DC, these contactors are of the block type design with 3 main poles.
AF116-AF140 contactors are mainly used for controlling 3-phase motors and power circuits up to 690 V AC, AF146 up to 1000 V AC
AF190-AF370 contactors are mainly used for controlling 3-phase motors and power circuits up to 1000 V AC, these contactors are of the block type design with 3 main poles.
AF contactors have built in surge protection and does not require any additional surge suppressors
