It carries an AC-2 rating of 15 kW at 400 V and an AC-3 rating of 18.5 kW at 500 V, so it handles the starting and running currents of induction motors up to that power class.
The AC-2 rating of 15 kW at 400 V covers slip-ring motor duty, where the contactor opens under reduced current. For auxiliary or control circuits, the contactor switches 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — these cover coil and signal loads. The mechanical life of 10 million operations means the contactor itself will outlast the panel in most cyclic applications.
