The Siemens 6SL3356-3AG38-1AA0 is a factory-replacement IPD (Interface and Protection) card for a SINAMICS S120 liquid-cooled Motor Module rated at 800 kW on a 500-690 VAC three-phase supply, 50/60 Hz, drawing 810 A. This is the spare part you pull when the drive's internal IPD board fails — not a full module, just the card that handles gate-drive isolation and fault monitoring inside the liquid-cooled chassis. Rated for 810 A continuous at the module's nominal voltage band, this IPD card directly supports the 800 kW output stage. The 500-690 VAC range covers 690 V class drives common in heavy industrial and marine installations where liquid cooling is specified for high-power density.
Export control is straightforward: AL N / ECCN EAR99H, so no special licensing for most destinations. RoHS compliant since April 2018;
One piece per unit, packaging quantity of 1. The kit is the IPD card only — no mounting hardware, no interconnect cables, no thermal interface material. The tech on site will need the existing screws and standoffs from the failed card; the replacement slides into the same slot in the liquid-cooled Motor Module frame. Group code R2SC and product group 4Q30 are Siemens internal classification tags that route this spare to the correct service logistics channel. If you are ordering through Siemens Industry Mall or a parts portal, those codes confirm you have the right variant for the 800 kW liquid-cooled platform.
