The ABB ACS800-104-0510-3+E205+V991 is an AC inverter drive in the ACS800-104 drive family, listed under Motors & Motor Controls, Drives, Motor Drives. The +E205 and +V991 suffix codes are ABB plus-code option identifiers and must match the build on the original purchase order; they change the module's delivered option content, not the base series identity.
Where this class sits in a panel
ACS800-104 modules are used to control industrial motors in cabinet-built drive lineups, so panel layout and bus connections dominate the integration work rather than DIN-rail footprint. The 130.00 kg figure confirms this is a cabinet-mounted module, not a drive that bolts to a sub-panel alongside standard control gear.
