What you're sourcing
The ABB ACS850-04-035A-5+E200+J400+K475 is an industrial AC drive from the ACS850-04 series, listed under the Motor Drives class. The full suffix string encodes factory-fit option codes (+E200, +J400, +K475), so the order code as written is what has to appear on the purchase order — dropping or substituting a plus-code yields a different BOM line. Cabinet mass is 6.99 kg, which is the figure a panel builder uses for handling and rail-mount loading rather than for selection — sizing is set by motor current and supply, not by grams.
Where it sits in the panel
This is a wall/cabinet-mount AC drive in ABB's industrial drives catalog, grouped under Motors & Motor Controls › Drives › Motor Drives alongside the ACS880-01 wall-mount family.
Frame comparison — not a drop-in
The ACS850-04 frame at 6.99 kg is bracketed by the ACS880-01-07A6-5 at 6.35 kg and the ACS880-01-021A-5 at 7.71 kg, but the mass spread tracks different current ratings and a different control platform — the ACS850 and ACS880 are separate generations, so frame weight alone does not make them interchangeable. A panel that was specified around the ACS880-01-07A6-5 (6.35 kg) is not confirmed as a like-for-like swap target for the ACS850-04-035A-5 at 6.99 kg without a cross-reference on current rating, footprint, and option codes; treat them as distinct BOM lines, not alternates.
