The Siemens 6SL3352-3AG37-4AA0 is a replacement Interface & Protection Device (IPD) card for the SINAMICS S120 air-cooled Motor Module rated 500-690V at 710kW. This is a spare part, not a standalone drive — it goes inside the Motor Module assembly to handle gate-drive isolation, fault detection, and DC-link monitoring. If you are rebuilding a failed S120 cabinet or stocking spares for a critical drive line, this is the board that sits between the Control Unit and the power stage. The product class is C: manufactured or produced to order, not stocked as a standard catalog item. That means each unit is built against a confirmed order — no off-the-shelf availability. Plan lead time accordingly when the line is down.
Because it is made to order (class C), the supply channel is quote-driven. Submit an RFQ with your quantity and target delivery window.
Compliance and regulatory notes
This is standard for power electronics with solder joints and component terminations — no special handling beyond normal industrial WEEE compliance.
Group code R2SC and product group 4Q30 are Siemens internal classification tags used for BOM and logistics routing. They do not affect physical fit but can help with cross-referencing in Siemens order tools.
