The ABB 3AXD50000268733 is an ACQ580-01 wall-mounted LV AC drive, built for water and wastewater duty — pumps, aerators, and filtration blowers in treatment plants. Frame size R4, wall-mounting, with a NEMA Type12 enclosure and IP55 ingress protection, so it stands up to hose-down washdown and dust in the pump house. Input is 208-240 V three-phase. Light-overload rating is 25 Hp at 75 A continuous; heavy-duty (constant-torque) rating is 20 Hp at 20 A. That split tells you the drive is sized for variable-torque loads — centrifugal pumps and fans — where the heavy-duty number governs conveyor or positive-displacement applications. Apparent power output is 30 kV·A.
Efficiency and thermal constraints
Rated IE2 efficiency class. Standby loss is 17 W — that's the quiescent draw when the motor is stopped but the DC bus is up. Ambient temperature ceiling is 40 °C; above that you derate output current per the drive's thermal curve (not shown here, but standard for the class). 50/60 Hz line frequency, no restriction.
