The line ships in the U31 enclosure form factor and is the part the buyer names on the BOM when the legacy ACS800-U31 frame is called out — not the newer ACS880-01 cabinet footprint and not the ACS580 general-purpose series. Listed weight is 45.36 kgs. That is a two-person lift and a real cabinet-mount load — plan the back-panel reinforcement and the rigging before the crate lands, not after. ## Where this part actually sits on the line An ACS800-U31 drive on a hot-strip or reversing mill earns its place because the platform holds strip tension through the roll bite and stays put next to the cabinets that bleed inverter-switching noise into everything else. Specifying the U31 frame keeps the control topology — adaptive programming, the drive-side fieldbus option slots, the DTC motor model — that the rest of the line was tuned around.","metaTitle":"ABB ACS800-U31-0120-5 Drive, 125 HP, 45.36 kg","metaDescription":"ABB ACS800-U31-0120-5 ACS800 series motor drive rated 125 HP, listed at 45.36 kgs.
