The ABB AF12-30-01-12 is a 3-pole contactor from the AF12 series, with one normally closed auxiliary contact and a wide-range coil accepting 48 to 130 V AC/DC. It is designed for controlling power circuits up to 690 V AC and 220 V DC, primarily for switching 3-phase motors and non-inductive or slightly inductive loads. The electronic coil interface handles large control voltage variations, so a single coil covers the full 48-130 V range without needing a separate pickup/hold circuit.
Application context
The 1NC auxiliary contact provides a feedback or interlock signal for the safety circuit or PLC input. For motor loads, size the overload relay separately to match the full-load current of the driven motor.
