What the order code actually is
The ABB ACS800-U4-0210-5+E208+E210+P901 is an industrial low-voltage AC drive in the ACS800-U4 wall-mount family, ordered here with the +E208, +E210 and +P901 option codes factory-fitted. The bare drive alone and a +E208/+E210/+P901-equipped unit are not the same line item, so the suffix has to match the PO character-for-character. It sits in the Motor Drives category (Motors & Motor Controls › Drives › Motor Drives), which is where anyone specifying it on a BOM expects to find the line.
Mechanical envelope for the panel builder
Chassis mass is 41.15 kg, which puts the unit on the edge of a two-person lift and shapes the backplate, gland-plate and lifting-eyelet decisions on the assembly floor. A drive this heavy is rarely a shelf swap — it wants a planned lift path and a panel that can carry the static load long-term.
In-class context on our desk
The same Motor Drives line on this desk carries the DCS880-S02-0680-05X0 (DC-drive sibling), the ACS880-01-156A-5 (the ACS880 successor generation) and the ACS550-U1-059A-4+B055 (older value line). They are siblings in the ABB drives catalogue, not confirmed drop-in alternates for this specific ACS800-U4-0210-5 suffix build — quoting any of them as a substitute would need an option-by-option cross-check, not a part-number swap.
