The ABB 3BBR0000090446 is the order code for an ACS880-01-260A-5 drive, built in frame size R8. This is the active-production variant of the ACS880-01 line, confirmed at lifecycle stage current.
Frame size R8 determines the mechanical footprint and the bus-bar / cable entry layout. For a panel build, verify the mounting dimensions against the existing cutout — R8 is a larger frame, so a retrofit into an R6 or R7 footprint requires a new backplate or adapter. The drive accepts the standard ACS880 option modules; slot assignments follow the same manual as the rest of the ACS880-01 family.
