The same part also carries AC-1 (resistive load) and AC-4 (plugging/reversing) utilisation categories, so it is not limited to motor starts — it can switch resistive heater banks or handle the higher arc stress of reversing duty, though the current rating differs under those conditions. Motor power capability is given across several voltage bands: 3 kW at 220–230 V, 5.5 kW at 380–415 V and 440 V, and 4 kW at 480 V, 500–600 V, and 660–690 V. These are the practical selection figures for a panel builder — pick the row matching your line voltage to confirm the contactor is sized for the motor nameplate. The 4 kW figure at 480 V is the one most often checked for North American 480 V three-phase installations. Heat dissipation is 3 W, which is low enough that thermal buildup in a dense DIN-rail cabinet is not a concern with this part alone.
