The Siemens 6SL3352-3AE37-5AA0 is a replacement IPD (Interface and Protection) card for the SINAMICS S120 air-cooled Motor Module range, rated for 380-480V and 400kW. It's a made-to-order spare (Product class C) — not a shelf-stocked commodity, so plan your procurement lead time accordingly. This card sits inside the Motor Module enclosure, handling the gate-drive interface and protection logic for the IGBT power stage. Out here in the grease, if that IPD card goes, the whole module drops — so having one on the shelf or in the BOM as a quoted spare is the difference between a quick swap and a line-down event.
RoHS compliant since 16-08-17, with a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w — standard for power electronics with soldered joints. The product group is 4Q30 and the group code is R2SC, which are Siemens internal classifications for ordering and catalog filtering.
