The Siemens 6SL3356-3AE37-5AA7 is a factory spare part: the Interface & Protection Device (IPD) card for a water-cooled (CuNi) SINAMICS S120 Motor Module rated at 400 kW on a 380-480 V 3-phase supply, 50/60 Hz, pulling 745 A. This is the control and protection board that sits between the drive controller and the power stage in the water-cooled chassis — not the power module itself, but the card that manages IGBT gating, desaturation detection, and feedback. If you are rebuilding a S120 water-cooled cabinet or holding a spare for a critical line, this is the exact card the BOM calls out.
