The ABB ACQ580-01-03A4-4 is a low-horsepower AC drive from the ACQ580-01 series, positioned for water and wastewater pumping duty rather than general-purpose HVAC or constant-torque mill loads. Catalog placement is Motors & Motor Controls › Drives › Motor Drives, and the part ships as a wall-mount package at 8.40 kgs, which is the figure a panel builder uses to size the backplate and lifting clearances during install.
What the ACQ580-01-03A4-4 is sized for
The ACQ580 product line is the ABB drive family engineered specifically for water and wastewater applications — pump curves, level control, and aeration rather than high-inertia mill spindles. The -01 frame is the wall-mount / cabinet-mount form factor, so the drive drops onto a standard cabinet backplate and takes its line and motor landings from the bottom, leaving the front face clear for the assistant keypad and parameter navigation. At 8.40 kgs the unit is a one-person lift for an installer working from a step ladder, but it still wants a reinforced cabinet shelf or a backplate rated for the mass once the cable glands and reactors are added. The water/wastewater positioning also means commissioning leans on the pump macros inside the drive rather than open-loop V/Hz tuning, so the first power-up is a parameter-set swap, not a tuning pass.
Where it sits against the ACH580 and ACH550 siblings
The closest catalog neighbor is the ACH580-01-014A-4 from the HVAC-flavored sister series, which lists at 6.80 kgs — a different application profile (building automation rather than pump stations) rather than a like-for-like swap. Drop-in replacement between the ACQ580-01-03A4-4 and the ACH580-01-014A-4 is not implied: the parameter sets, macros, and fieldbus defaults diverge by series even when the mechanical frame overlaps.
Sourcing posture and what to send with the RFQ
The ACQ580-01-03A4-4 carries the ABB brand and is quoted to order against a procurement RFQ — specify the order code, the destination country's voltage convention, and any required option cards (fieldbus adapter, IP upgrade, brake chopper) so the BOM line closes on a single matched configuration. For panel retrofits coming off an ACH550-UH-023A-4 line, treat the ACQ580-01-03A4-4 as a new specification rather than a series-internal cross, since the legacy ACH550 frame is a heavier 11.34 kgs unit built to an earlier mechanical generation.
