The Siemens 6SL3357-3AG41-0AA7 is a replacement IPD (Interface and Protection) card for the SINAMICS S120 water-cooled Active Line Module with CuNi heat sink, rated at 1100 kW, 750-1035 V DC, and 1147 A. This is the control and interface board that manages the module's line-side converter, DC-link regulation, and protective functions — not a power stage itself, but the logic that keeps the power stage running within its limits.
