Spare fan for the 100 mm booksize S220
The 6SL5166-0AD00-0AA0 is the spare-part fan module for the SINAMICS S220 in the 100 mm booksize form factor — the cooling element that keeps the drive's heatsink path intact when the original unit has been in service long enough to need replacement.
Group code R220, product group X0HX — what those tags mean for the BOM
The order-code header carries Group Code R220 and Product Group X0HX (cites:,) — Siemens-internal classification lines that the back-office uses to route the order to the correct product family; they confirm the 6SL5166-0AD00-0AA0 belongs with the SINAMICS drive accessories under the R220 group, not the SIMATIC or SIRIUS lines a panel builder might otherwise associate with that group code prefix. Packaging quantity is 1 Piece (cites:,) under Product Family Ordering Data Overview (cites:) — the unit is the spare fan itself, not a service kit or a multi-pack.
