Duty ratings and application fit
The 3ABD00046045-D: The normal-use rating of 200 kW / 363 A suits continuous-duty centrifugal pumps and fans in water and wastewater service. For higher starting torque or cyclic loads, the heavy-duty curve delivers 160 kW / 293 A — enough margin for a 200 kW motor on a variable-torque profile without oversizing the drive. Light-overload use is rated at 200 kW / 345 A, matching the normal-use power but with slightly lower current headroom — a distinction that matters when the load profile includes brief overloads rather than sustained heavy duty.
