The Siemens 6SL3358-3AE41-7BA0 is a replacement IPD (Interface & Protection) card for the SINAMICS S120 liquid-cooled Basic Line Module rated at 830 kW, 380-480 V three-phase, 50/60 Hz, and 1730 A. This is the spare part that goes inside the line module — not the module itself — so if you're servicing a liquid-cooled drive cabinet and the control/protection board on the BLM is shot, this is the card you swap in.
Listed as active in the manufacturer's lifecycle system. The product class is C — manufactured or produced to order, which means it is not a stocked shelf item; each unit is built against a confirmed order. That aligns with the made-to-order nature of large liquid-cooled drive spares. RoHS compliant since 06-12-17, with a REACH Article 33 disclosure for lead (CAS 7439-92-1) above 0.1% w/w.
This card mounts inside the liquid-cooled Basic Line Module chassis. The 1730 A rating matches the BLM's line-side current handling at 380-480 V. If you are rebuilding a SINAMICS S120 cabinet with a BLM that has lost its IPD board, verify the module frame size and firmware compatibility — the card is the control interface for the line-side thyristor/IGBT bridge and protection circuits. Group code R2SC and product group 4Q30 are the internal Siemens classification tags; they help when cross-referencing against a BOM or ordering through Siemens Industry Mall.
