The 3ABD00046733-D: The normal-use rating (90 kW, 169 A) covers most constant-torque fan and pump applications. The heavy-duty rating (75 kW, 145 A) applies when the motor demands higher peak torque or a more demanding duty cycle — conveyors, crushers, extruders. Matching the drive's duty rating to the actual motor load profile avoids nuisance tripping and keeps the IGBT junction temperatures within design limits.
Efficiency class
Rated IE2 efficiency. For applications requiring IE3 or IE4 to meet local energy regulations, check whether the motor and drive combination must meet a higher class; the drive itself does not carry a higher efficiency label.
