Spare Part for the Drive Cabinet
The Siemens 6SL3353-3AG31-4AB0 is a replacement IPD card for the SINAMICS S150 air-cooled Active Line Module — the interface board that handles the line-side power conversion control. This is a built-for-the-pit spare: if the IPD on your S150 drive cabinet fails, this card swaps in to get the line back up without replacing the whole module. It is classified as Product class C — manufactured or produced to order, not a stocked shelf item. That means lead time is tied to the build schedule, not a bin count. Confirm availability against an RFQ before the shutdown window closes.
RoHS compliant since 01-07-17.
Sourcing and Fit Note
Group Code R2SC and Product Group 4Q30 are the internal Siemens classification — useful when cross-referencing against a drive cabinet bill of materials or a Siemens spare-parts portal search. The packaging unit is one piece, non-returnable per the product class definition.
