The 3ABD00039390-D: Heavy-duty use derates to 250 kW / 429 A; light-overload use holds at 315 kW / 575 A. Frequency range 47.5 to 63 Hz.
Normal-duty 585 A is the continuous current rating for typical variable-torque loads (fans, pumps). Heavy-duty 429 A covers constant-torque or high-starting-torque applications (conveyors, crushers). The 380-415 V input range matches standard European low-voltage networks. Frame R11 and IP20 mean it's intended for cabinet mounting with additional enclosure protection against dust and moisture.
