The Siemens 6SL3356-3AG35-8AA0 is a replacement IPD card for the SINAMICS S120 liquid-cooled Motor Module rated at 560 kW on a 500-690V 3AC supply, 50/60 Hz, pulling 575 A. This is the board-level spare that goes inside the drive module — not the module itself. Group code R2SC and product group 4Q30 are the internal Siemens classification tags. They help with cross-referencing in Siemens ordering tools but don't affect electrical fit.
Lifecycle stage is marked as mature, and the product class is C — manufactured or produced to order, not a stocked shelf item. That means it's built when you order it, so lead time is driven by Siemens production schedule, not a warehouse pick. RoHS compliance effective since 01-04-18, and REACH Article 33 duty to inform applies because the candidate list includes lead (CAS-No. 7439-92-1) above 0.1% w/w.
The 575 A rating at 500-690V 3AC matches the current draw of a 560 kW liquid-cooled motor under full load. If your existing IPD card has failed in a SINAMICS S120 liquid-cooled module of that power class, this is the direct board-level swap — no re-engineering, no adapter. Because it's a replacement card (spare part), not a complete module, you're swapping the control/power interface board inside the existing housing. Verify the module frame size and firmware compatibility against the Siemens manual before ordering.
