What the order code covers
The ABB ACS380-040C-03A3-4+K475 sits inside the ACS380 machine-drive family, a compact platform ABB positions for direct-on-line integration into OEM panels and small standalone cabinets. The +K475 suffix denotes the factory-installed option bundle ordered against this code, which is the variant the spec sheet and the BOM line are both pinned to. Catalog placement lands it under Motors & Motor Controls, then Drives, then Motor Drives — which is the trail a procurement system will walk when the RFQ is keyed off the order code.
Adjacent variant for cross-reference
Peer MPN ACS380-040C-02A6-4+K490 sits in the same 040C frame and is listed at 1.81 kgs. Procurement should confirm whether the BOM locks the +K475 option suffix or only the frame before substituting.
