What lands on the BOM
The ABB ACS800-U11-0100-5 is the AC drive line ordered under the ASEA BROWN BOVERI brand in the ACS800-U11 series, filed as a Motor Drive under Motors & Motor Controls. It carries a listed weight of 45.36 kgs, which is heavy enough to dictate two-person lift and panel-mount bracing on installation, not a bench swap.
Where it sits on the line
ACS800-U11-0100-5 drives are sized as the heavy-industrial wall-mount AC drive in the ACS800 family — the unit that lives in the MCC corner, not on the machine face — so the swap-in question for a maintenance tech is panel footprint and cable landing, not firmware.
Cross-shop against real siblings
The credible second-source for an ACS800-U11-0100-5 retrofit is the ACS880-01-156A-5 — same ABB industrial-drive wall-mount slot, listed at 55.00 kgs versus 45.36 kgs for the ACS800. It is the same class of unit, not a direct pin-for-pin swap, and the panel-builder should expect a footprint review before quoting it as a like-for-like.
