The heavy-duty (PhD) rating of 250 kW / 414 A applies when you need higher overload capacity — for crushers, extruders, or any application with sustained peak torque demands. Light-overload (PlD) at 400 kW / 573 A is a lighter duty cycle, useful where the load profile is mostly steady-state with infrequent short peaks. Matching the right duty class to your application avoids oversizing or nuisance tripping.
