The Siemens 6SL3351-3AH31-2DB0 is a Replacement IPD card for the SINAMICS G150 drive series — a spare part, not a full drive module. It carries Group Code R2SC and Product Group 4Q30, which are Siemens internal classification codes used for ordering and BOM traceability. Product class C means it is manufactured or produced to order and cannot be reused, re-utilized, or returned for credit — so confirm fit before committing the line.
