The 3ABD50000039029 is an ABB ACQ580-01-033A-4 LV AC wall-mounted drive, purpose-built for water and wastewater applications. It delivers 15 kW output power at 32 A in normal-duty use (light overload) and 11 kW at 24.6 A in heavy-duty use, on a 380-480 V three-phase supply at 47.5-63 Hz. Frame size R3, IP21 enclosure, NEMA 1.
Normal-duty (light overload) at 15 kW / 32 A is the rating for pump and fan curves where peak demand stays under 110 % for short intervals. Heavy-duty at 11 kW / 24.6 A covers constant-torque loads like screw feeders or positive-displacement pumps that need 150 % overload for 60 seconds. If your motor plate says 15 kW and the load is a centrifugal pump, the normal-duty line fits. For a 11 kW positive-displacement pump, the heavy-duty column is the one to quote against. The IE2 efficiency class means the drive itself meets the IE2 standard for power conversion — not the motor, the drive. On a retrofit where the existing motor is IE1 or IE2, this drive won't force a motor upgrade on efficiency grounds alone.
