What the line is and why the code matters
The ABB ACS380-040S-17A0-4 is an ACS380-series motor drive from the Motor Drives sub-category under the broader Drives heading, and the part number itself is the line item a buyer carries into the BOM.
Frame placement in the ACS380 family
Within the ACS380 family the 17A0-4 sits above the 06A9-2 and 04A0-4 frames, and the ACS380-040C-02A6-4+K490 variant carries a +K490 option suffix that changes its build rather than its current class.
Sourcing posture
Buyers needing a confirmed lifecycle read should request that with the quote.
