Motor ratings and duty cycles
The 3RT1035-1AG60-1AA0: For motor switching, the AC-2 rating at 400 V is 18.5 kW — this is the figure that governs the contactor's life on wound-rotor or slip-ring motor loads. At 500 V the rating rises to 22 kW, and at 690 V it drops to 11.4 kW, reflecting the voltage-dependent switching stress. The AC-3 maximum mechanical switching rate is 1 000 operations per hour, while AC-4 (plugging/inching) is limited to 300 per hour — a meaningful constraint if the application involves frequent reversing.
Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, and the degree of pollution is rated 3 (conductive pollution or dry non-conductive pollution that becomes conductive).
