What the part is
The ABB ACS800-104-0215-5+G304 is an industrial motor drive in the ACS800-104 series, ordered under the ABB Drives category with motor drives as the working sub-class, and the +G304 option string travels with the base code on the nameplate. Net weight is 38.10 kgs, which makes it a two-person lift and drives the panel-mounting layout choice around the cooling circuit that the ACS800-104 chassis requires.
Where this class sits in a panel
ACS800-104 units are the liquid-cooled cabinet-mount members of the ACS800 family, so the install question is coolant loop integrity and cabinet heat rejection. At 38.10 kgs the unit sits inside the cabinet on its own mounting frame; handling and craning into position is the practical concern, not rail-clip retention.
Functional second-source check
The closest current-generation ABB cross-shop is the ACS880-01-156A-5 at 55.00 kgs — same drives category and same motor-drive sub-class, but a different chassis and a different mass, so it is not a panel-for-panel drop-in and the wiring, gland layout, and cooling strategy have to be reworked. Two adjacent siblings appear in the same family for context only: the DCS880-S02-0680-05X0 is a DC drive at 40.00 kgs, and the ACS550-U1-059A-4+B055 is a legacy AC drive at 36.29 kgs; neither is a functional swap for the ACS800-104, and treating them as substitutes will fail commissioning.
Sourcing posture
For a buyer cross-shopping against the ACS880-01-156A-5, the deciding facts are chassis and mass: ACS800-104-0215-5+G304 at 38.10 kgs versus ACS880-01-156A-5 at 55.00 kgs, which forces a cabinet-layout review before any swap is signed off.
