What it is on the BOM line
The ACS800-U1-0006-5-N660: The unit is listed at 7.71 kgs, which is the figure that drives lift-and-mount handling on the shop floor rather than any electrical fit decision; a single installer can set it on the backplate, but the mass matters when the drive is being added to an existing MCC cubicle and the panel builder is checking the door-load rating.
Class and what the series is for
ACS800-U1-0006-5-N660 sits on the path Motors & Motor Controls / Drives / Motor Drives, marked as the wall-mount form factor of the ACS800 family. The record identifies the order code; the cited fields cover category position only, not voltage class, current frame, or IP rating.
Cross-shop against the ACS880 wall-mount line
The ledger carries three ACS880-01 peers that sit in the same wall-mount class: ACS880-01-07A6-5, ACS880-01-021A-5, and ACS880-01-052A-5. The closest in listed mass is ACS880-01-021A-5 at 7.71 kgs — identical to the ACS800-U1-0006-5-N660 on weight, which means the same lift and the same backplate pattern carry straight across. ACS880-01-07A6-5 is the lighter neighbour at 6.35 kgs, and ACS880-01-052A-5 is the heavier one at 9.07 kgs, so the choice between them is current/frame, not panel real estate. Two cautions belong on that cross-shop before anyone calls it a drop-in replacement: the ACS880 generation uses a different control board layout and a different firmware toolchain (Drive Composer rather than DriveWindow), and the parameter set is reorganised. The baseplate and connection landing points are close enough that the rewiring on a like-for-like current rating is modest, but the commissioning file does not import cleanly and the application macro has to be rebuilt — that is the work the integrator carries, not the panel builder.
