The Siemens 6SL3357-3AG41-3AR8 is a factory-original replacement IPD (Interface and Protection Device) card for the SINAMICS S120 water-cooled (CuNi) Active Line Module. It is the control and interface board that manages the line-side converter stage in a 1400 kW, 750-1035 V DC drive system. Rated at 1270 A continuous DC link current, this IPD card includes an FPGA that enables overload operation at 200% reactive current — critical for applications where the drive must supply short-duration reactive power to stabilize the grid or motor flux during transient events.
Lead time depends on the Siemens production queue; plan for a typical made-to-order horizon rather than same-day dispatch.
RoHS compliant since 01-04-18.
