The ABB ACS800-U4-0210-7+P901 is a cabinet-format AC drive on the Motor Drives line, ordered as a complete AC cabinet drive under the ASEA BROWN BOVERI traceable nameplate. The listing places it under Motors & Motor Controls > Drives > Motor Drives, consistent with how a panel builder or systems integrator would file it.
Panel fit versus an ACS550-specified cabinet
Buyers running ACS550-spec cabinets often ask whether the ACS800-U4-0210-7+P901 drops in without rewiring; the listing carries the ABB ACS550-U1-157A-4 (89.81 kg) as a same-class peer, so the two are in the same cabinet-drive weight band but they are not the same family. Mounting envelope, control-terminal map and fieldbus option cards are family-specific, so a drop-in swap should not be assumed — confirm the original panel's backplate cutout, the control-terminal layout, and the firmware/parameter file path against the receiving unit before committing the install window.
