What it is and where the class sits
The ABB ACQ580-01-062A-4 is a wall-mount frequency inverter out of the ACQ580 series, the ABB water and wastewater drive family positioned for pump, fan, and constant-torque process loads. It carries a 62 A frame rating and weighs 8.62 kg, which puts it in the mid-power bracket of the ACQ580-01 single-drive lineup — large enough for industrial pump skids and process fans, compact enough to fit a standard cabinet cut-out. ACQ580 drives ship with embedded pump and blower macros and an adaptive programming environment, so the commissioning path is shorter than a general-purpose drive when the application is flow control rather than precision motion.
Why the frame current matters on the BOM line
For a sourcing buyer, the load-bearing figure on a -062A-4 order code is the 62 A frame current — it is the rating that drives branch protection sizing, cable selection, and the upstream contactor coordination, not the marketing horsepower class. At 8.62 kg the unit is a two-person lift onto a backplate and fits the same footprint pattern as the rest of the ACQ580-01 frame, so existing panel cut-outs and gland plates are reused without rework on a like-for-like replacement.
Where it does and does not slot against the siblings
The ACH550-UH-023A-4 is a legacy ACH550 unit at 11.34 kg and a different current frame, so it belongs in a retrofit conversation only, not a direct cross-reference against an ACQ580-01-062A-4 BOM line.
