The ABB 3AXD50000761128 is an ACQ580-01 wall-mounted LV AC drive, built for water and wastewater applications. It accepts 3-phase input at 525 to 600 V, 50/60 Hz, and delivers UL light-overload output of 2 Hp at 2.7 A, or 1.5 Hp heavy-duty at 1.5 A. The enclosure is IP55 with NEMA Type12 rating, suited for washdown or dusty environments without an additional cabinet.
The UL heavy-duty rating (1.5 Hp, 1.5 A) governs continuous motor operation at rated current — that is the number to use for a constant-torque pump or fan application where the load stays near nameplate. The light-overload rating (2 Hp, 2.7 A) allows a 33 % current margin for 60-second overloads, typical for variable-torque loads like centrifugal pumps. The 525-600 V input range covers 480 V and 575 V nominal systems with margin; confirm your supply voltage falls within this band.
Wall-mount design with IP55 / NEMA 12 protection. This means the drive can be installed directly in a non-conditioned area with dust or hose-down exposure, as long as it is not submerged. No separate enclosure is required for most indoor water-treatment environments. Verify the ambient temperature range in the full datasheet before final placement.
