The ABB 3ABD00045727-D is an ACQ580-01-145A-4+B056, a wall-mounted LV AC drive built for water and wastewater duty. Input voltage range is 380 to 500 V three-phase, and it handles line frequencies from 47.5 to 63 Hz — so it works on 50 or 60 Hz systems without a hiccup. Enclosure is IP55 with a NEMA Type12 rating, meaning it's sealed against dust and hose-down water — fine for pump stations or treatment plants where the air's damp and dirty. Frame size is R6, which tells you the physical footprint and cooling requirements for panel layout.
Efficiency and duty ratings
This drive carries an IE2 efficiency level. That's the baseline for the class — it won't win any energy awards, but it's the standard fit for most industrial water applications where the motor's already sized for the load. The normal-use (light-overload) output is 75 kW at 138 A, while the heavy-duty curve drops to 55 kW at 105 A. If you're running a centrifugal pump that rarely hits full torque, the normal-use rating is your number. For a positive-displacement pump or a conveyor with frequent starts, the heavy-duty rating is the one that keeps the drive out of thermal trouble.
