It carries a 30 kW rating at 500 V under AC-3 duty — that's the standard motor-switching curve for squirrel-cage induction motors — and 22 kW at 400 V under AC-2 duty, which covers slip-ring motors or reversing applications where the contactor makes and breaks load current at reduced frequency.
Termination and wiring
Main current circuit uses screw-type terminals. Accepts solid conductors 2x (0.25... 2.5 mm²) and stranded conductors 2x (0.75... 25 mm²), with a separate entry for 2x (0.75... 16 mm²) solid or stranded. That range covers most panel wiring from control-circuit signal wires up to motor power cables.
