The Siemens 6SL3353-3AE41-2AA0 is a replacement Interface and Protection Device (IPD) card for the SINAMICS S120 air-cooled Active Line Module. This is the spare part that goes into the module's control section, not the line module itself. If your Active Line Module has a failed IPD board, this is the factory-authorized swap-in. The part carries a Group Code of R2SC and Product Group 4Q30, which are Siemens internal classification codes used for ordering and logistics routing. These are not functional ratings but matter when generating a purchase order through Siemens channels.
Verify your end-user if shipping outside routine industrial channels. This is a standard SVHC disclosure for lead in electronic components; it does not restrict sale but must be passed down the supply chain per Art. 33.
Integration Note
This IPD card mounts inside the SINAMICS S120 air-cooled Active Line Module chassis. It is not a standalone module; it plugs onto the module's backplane board. The replacement procedure requires power-down, ESD precautions, and careful handling of the ribbon cables connecting to the power board. No field rewiring is involved — it is a board-level swap.
