What the line shows
The ABB ACS850-04-08A0-5+J410+K473+L502 is a configured drive in the ACS850 family — base frame ACS850-04 with current code 08A0-5 and the factory option string +J410+K473+L502 already applied to the build. It lands in the Motor Drives catalog line under Drives, so a buyer reading the part number knows it sits in the industrial drive class rather than soft starters or motor protection. Vendor identity on record is ABB; the listing text labels the drive as ACS850 by ASEA BROWN BOVERI for procurement paperwork where the legacy name still appears. The full order string on the listing is 2.86 kgs, which is the bench weight a panel-builder needs to plan a single-person lift and a cabinet back-plane that can carry the drive plus its cooling airflow path.
Sourcing posture
For a BOM line that needs this exact configured order code, the working posture is to quote it to order: hand the full string with options +J410, +K473, +L502 intact so the option set isn't quietly dropped on the way through, and let the distributor desk return availability against that exact build.
Where the part fits against the ACS880 family
A buyer cross-shopping a panel built around ACS880-01-11A0-5 should not assume the ACS850-04-08A0-5+J410+K473+L502 is a drop-in: ACS850-04 is the older frame series and ACS880-01 is the successor architecture, so the fieldbus slice, terminal map, and option-card slot count will not match without rewiring — the part number change is a generation change, not a same-frame current step.
