What lands on the BOM
The ACS800-104-0460-5+E205+Q950+V991 is the configured order code for an ACS800-104 regenerative single-drive module, with the +E205, +Q950 and +V991 option suffixes built into the order string as a single line. Mass on the order is 130.00 kgs — this is a chassis that arrives on a pallet, not a shelf item, and panel layout has to budget the swing room and the floor load before the crate comes off the truck.
Where the class sits
The part files under Motors & Motor Controls, then Drives, then Motor Drives — i.e. the industrial low-voltage AC drive class used to run three-phase induction and synchronous motors from a fixed mains supply, with the ACS800-104 specifically being the regenerative IGBT supply / single-drive module that feeds a common DC bus rather than a stand-alone wall-mount unit.
Class-peer reference
The ACS880-01-156A-5 is a true frame-class peer in the same ABB drive family — same function (low-voltage AC motor drive) but a wall-mount form factor at 55.00 kgs against this unit's 130.00 kgs. The mechanical delta is large enough that a panel cut around the ACS880 will not accept the ACS800-104 without rework; the electrical hook-up and fieldbus slice are a separate question that needs the nameplate-to-nameplate check rather than a yes/no call here.
