The Siemens 6SL3357-3AE41-4AA7 is a spare IPD (Interface and Protection) card designed specifically for the water-cooled (CuNi) SINAMICS S120 Active Line Module rated at 900 kW. It handles 1573 A across a 570-720 V DC link. This is a line-side module card — the interface between the drive controller and the active front end — not a standalone drive. If you're rebuilding a S120 water-cooled ALM or swapping a failed card on a 900 kW line, this is the factory spare.
