What lands on the BOM line
The ABB ACS355-03U-09A8-2+B063+F278 is a 2.2 kW ACS355-series drive configured with the +B063 and +F278 factory option codes, and it sits squarely in the Motor Drives category as a low-voltage variable-frequency drive for small-motor applications. Chassis weight is 13.15 kgs, which is enough mass that a panel builder plans the mounting footprint and the lifting path rather than treating it as a drop-on-the-DIN-rail accessory.
What +B063 and +F278 do to the build
The +B063 and +F278 suffixes are ordered factory option codes appended to the base ACS355-03U-09A8-2 code, so they ship fitted at the ABB factory and arrive in the crate as a single nameplate — no field retrofit, no loose accessory box to misplace during panel build. Because the options are factory-fitted, the integrator reads one nameplate and one part number on the delivery, which keeps the declaration pack and the BOM trace to a single line item.
Where it sits against the same-class siblings
Against the ACS380-040C-032A-4+K475, the ACS355-03U-09A8-2+B063+F278 chassis is more than twice as heavy at 13.15 kgs versus 5.90 kgs — the kind of delta that changes panel layout and lifting hardware rather than just paperwork. The ACH580-VCR-027A-4 and ACH550-UH-023A-4 siblings land in the same Motor Drives line at 13.61 kgs and 11.34 kgs respectively, so they bracket the ACS355 chassis on weight without breaking the class — relevant when the BOM needs a generation-flexible second source.
