Normal-use vs heavy-duty — which rating governs your motor
The 3ABD00048320-D: The normal-use curve (132 kW, 246 A) is the catalog rating for a standard variable-torque load like a fan or pump. The heavy-duty curve (110 kW, 206 A) applies for constant-torque loads — conveyors, extruders, positive-displacement pumps — where the drive must deliver full torque across the speed range. If your motor plate is 132 kW and the load is constant-torque, you need the heavy-duty column: that motor will pull the drive into overload protection. Match the duty class to the load profile, not the motor nameplate. A light-overload rating is also listed at 132 kW and 234 A — this is the same power as normal use but with a slightly lower current limit, likely reflecting a different overload profile for applications with infrequent peak demands.
