What the line is
The ABB ACS800-104-0260-5+V991 is an AC inverter drive from the ACS800 platform, catalogued under Motor Drives and built for three-phase motor control in industrial panels. Because the package mass is 130.00 kgs on the spec sheet, plan for floor-standing or braced enclosure mounting rather than DIN-rail — that figure also drives lift-gear and handling time on site.
Adjacent-class parts worth a look
An ACS880-01-156A-5 sits in the same Motor Drives category and is the most common cross-shop candidate an importer will ask about; it is a wall-mount ACS880 unit at 55.00 kgs, not a verified substitute for the ACS800-104. An ACS550-U1-157A-4 (89.81 kgs) and an ACS880-01-065A-5 (23.13 kgs) appear as further adjacent-class Motor Drives entries from the same brand family and are listed here for orientation only — none of them is asserted as a drop-in replacement for ACS800-104-0260-5+V991.
Integration notes
Storage and operating temperature derating curves, EMC filter grounding, and fieldbus option slotting for the ACS800-104 platform are the kind of datasheet-level items the panel builder should pull from the official ABB manual before commissioning; the figures themselves are not present in this evidence bundle.
