What this card does in the drive
The 6SL3358-3AG41-3BA0 is a replacement IPD (Interface and Protection Device) card for the liquid-cooled SINAMICS S120 Basic Line Module rated 1100 kW at 500-690 V AC three-phase, 50/60 Hz, 1300 A. It is the control and protection interface board that sits between the drive control unit and the power stage — not a standalone module, but the spare board you swap when the original fails on a large liquid-cooled line. Rated for 1300 A continuous at the module's nominal voltage band, this card handles the gate-drive signals, DC-link voltage sensing, and fault isolation for the IGBT stack inside the BLM. A failed IPD typically takes down the entire drive; having this spare on the shelf cuts mean-time-to-repair from weeks to hours.
