Duty ratings that matter
The 3ABD00039312-D: Normal-use output is 250 kW at 505 A, but the heavy-duty rating drops to 200 kW at 361 A — that's the figure to size against for constant-torque loads like conveyors or positive-displacement pumps. Light-overload use (typically variable-torque fans and centrifugal pumps) sits at 250 kW and 485 A, close to the normal-use line.
