What you're looking at
The ABB ACS380-040C-04A0-4+K475 is an ACS380-series drive in the motor drives line under Drives within Motors & Motor Controls. Chassis weight is 1.81 kg.
Why the suffix matters on the order code
The +K475 suffix is part of the orderable part number, not a field-installed accessory, so the BOM line has to carry it verbatim — quoting 04A0-4 without the suffix will land a different factory build. The 04A0 current class is encoded in the order code itself; the suffix is the variant discriminator on an otherwise common chassis.
Cross-shop within the same chassis
The 02A6-4+K490 peer (ACS380-040C-02A6-4+K490) is the closest cross-shop candidate on this line — it shares the 1.81 kg chassis and the same 040C frame, with the current class and the option suffix being the only differences in the order code. A panel specified around the 02A6-4+K490 is on the same footprint, so the swap is a parameter/parameter-set change, not a panel rework — but the motor's current draw has to land inside the 04A0 rating of this build, not the 02A6 rating of that one. The base 04A0-4 unit (ACS380-040S-04A0-4) carries the same 1.81 kg weight and confirms the frame is the constant.
