The ABB 3AXD50000761135 is an ACQ580-01 wall-mounted LV AC drive, sized for water and wastewater applications per the listing. It accepts a 525... 600 V three-phase input at 50/60 Hz and delivers a UL light-overload output of 3 Hp at 3.9 A (575 V) or a heavy-duty output of 2 Hp at 2 A.
Rated IP55 and NEMA Type12, this drive is built for indoor environments where dust and dripping water are present — typical for pump rooms and treatment plant walls. The NEMA Type12 rating means it resists falling dirt and non-corrosive liquids; the IP55 rating confirms protection against water jets from any direction. Mount it with the gland plate facing down to maintain the seal path.
Ratings and selection
The light-overload rating (3 Hp, 3.9 A) is the continuous capability for variable-torque loads like centrifugal pumps and fans. The heavy-duty rating (2 Hp, 2 A) applies for constant-torque loads or when the drive must deliver 150 % current for 60 seconds. If your motor nameplate falls between these curves, size to the heavy-duty line to avoid nuisance tripping.
