Drive specs for the BOM line
The ABB 3ABD00046037-D is an ACQ580-01 wall-mounted LV AC drive, R4 frame, rated 37 kW normal use at 73 A output current on a 380-500 V three-phase supply. Heavy-duty rating is 30 kW / 61 A; light-overload rating is 37 kW / 68.4 A — so the normal-use figure governs the pump or fan curve, while the heavy-duty number matters for constant-torque loads like conveyors or screw feeders. Frequency range is 47.5-63 Hz, covering 50/60 Hz mains. IP21 with NEMA Type 1 enclosure means it's indoor-only, no washdown — fine for a dry electrical room or MCC house, not for a wet process floor. IE2 efficiency class meets the base level for variable-torque applications; if your site mandates IE3 or IE4 for the motor, the drive itself doesn't impose a penalty, but verify the motor-drive pair on the efficiency curve.
