What the order code carries
The ABB ACS880-01-040A-5+K475 is a wall-mount industrial drive from the ACS880-01 family, sized in the 40 A current frame and tagged with the +K475 option code on the standard ACS880-01-040A-5 base unit. It catalogs under Motors & Motor Controls, in the Drives / Motor Drives line, and the option suffix is how ABB distinguishes this configured variant from the bare 40 A frame. The 18.60 kgs figure drives bracket selection and wall reinforcement on a cabinet-mount install, since the unit ships as a through-hole module rather than a panel-cut component.
Where this class of drive fits an application
ACS880-01 series units are wall-mount drives in the Motor Drives line, used to run induction and permanent-magnet motors in industrial cabinets such as pump, fan, conveyor and compressor cells. The +K475 suffix is an option pack layered on the base drive; common ACS880-01 option codes cover extended I/O, communication cards, or functional-safety modules, but the specific scope of K475 is not enumerated in the listing and needs the ABB configuration sheet.
Frame sizing against the ACS880-01 family
The bare ACS880-01-040A-5 is the closest same-frame sibling and is the natural cross-reference if the +K475 option code is unavailable. Same power stage, same cabinet footprint, same control firmware line — the delta is the option pack on the +K475 variant, which has to be evaluated against what the +K475 actually delivers before treating one as a functional substitute for the other.
