What it is
The ABB ACS800-U1-0005-5+P901 is an AC drive on the Motors & Motor Controls / Drives / Motor Drives line, carrying the +P901 suffix that ABB applies to a specific option/config code on the ACS800-U1 wall-mount frame. Series is ACS800-U1 — the wall-mount single-drive family of the ACS800 platform — and the unit ships at 4.54 kgs, which keeps it a one-person carry for panel swap or line-down replacement work.
Same-frame peer for cross-shopping
The ACS880-01-11A0-5 sits in the same Motor Drives category and posts the same 4.54 kgs figure on record, so it's the closest weight-class peer for a buyer cross-shopping the ACS800-U1-0005-5+P901 — though it belongs to the newer ACS880 platform and is not a literal drop-in for the ACS800 BOM line without a platform-level engineering check. The ACS880-01-07A6-5 and ACS880-01-021A-5 also live on the Motor Drives line but list at 6.35 kgs and 7.71 kgs respectively, which flags a different current frame inside the ACS880 family and rules them out as like-for-like substitutes for the ACS800-U1-0005-5+P901.
