The Siemens 6SL3357-3AG41-3AR4 is a factory-original spare part — a replacement IPD (Interface and Protection Device) card designed for the liquid-cooled SINAMICS S120 Active Line Module rated at 1400 kW. It operates on a 500-690 V three-phase supply at 50/60 Hz and is rated for 1270 A in overload operation at 200% reactive current. Per the datasheet, this is the FPGA variant of the IPD card, which governs the module's control and protection logic.
REACH Article 33 duty to inform applies: the part contains lead (CAS-No. 7439-92-1) at >0.1% w/w, which must be declared in the supply chain documentation. Export control regulations are AL: N / ECCN: N, meaning no special export license is required for most destinations. The group code is R2SC and the product group is 4Q30 — these are Siemens internal classification codes used for ordering and logistics routing, not functional specs.
Deployment Context
This IPD card mounts inside the liquid-cooled SINAMICS S120 Active Line Module enclosure — it is not a standalone module. The 1400 kW rating places it in large-drive applications: high-power pumps, compressors, conveyors, or marine propulsion drives where liquid cooling is specified for thermal management. The 200% reactive current overload capability is sized for applications requiring high transient torque or regenerative braking.
