What this part is
The 6SL5166-3AB00-0AA0 is a Siemens spare-part DC link cover for the 50 mm line/motor module in the SINAMICS S220 drive family — it is the mechanical shroud that fits over the DC link section of that specific module width, not a converter or a power module itself.
Lifecycle and supply class
Lifecycle status for 6SL5166-3AB00-0AA0 is recorded as current — the part is still being supplied as a service spare against SINAMICS S220 line/motor modules. Siemens classifies the item under product class C: produced to order, non-returnable and not credit-eligible — typical for a made-to-order spare that is pulled from the same production routing as the parent drive line.
Compliance and packaging
Export control is AL:N / ECCN:EAR99H — no export licence required for the standard cross-border shipment, which keeps the spare-part kitting route straightforward for overseas service calls. Supplied as 1 Piece per order unit, packaging quantity 1, consistent with how Siemens ships low-volume mechanical spares against a service BOM rather than a bulk hardware buy.
