The ABB ACS800-U11-0020-5 is an AC drive from the ACS800-U11 series, sitting in the Motor Drives line under Motors & Motor Controls. The order code, manufacturer, and class carry the same identifier across the spec line — there's no variant suffix to disambiguate. Listed mass is 29.48 kgs. That is the figure that drives the lift-assist plan on site and the cabinet-floor load rating; two techs and a hoist are the realistic handling profile, not a one-person carry.
What the page does not give you
Voltage class, current rating, frame size, IP rating, fieldbus options, and conformal-coating code are not on this spec line. Those are the figures a controls-integrator would normally weigh before specifying into a BOM, and they live on the full datasheet rather than in the order-code row.
