The Siemens 6SL3357-3AG41-6AA8 is a replacement IPD (Interface and Protection Device) card for the water-cooled (CuNi) SINAMICS S120 Active Line Module rated at 1700 kW. It handles 1740 A continuous on a 750-1035 V DC bus and carries an FPGA for the control-loop interface. This is the board-level spare that goes inside the module frame — not the complete line module itself.
RoHS compliant since 01-04-18. REACH Article 33 duty-to-inform applies: the part contains Lead (CAS-No. 7439-92-1) above the 0.1% threshold.
