The Siemens 6SL3357-3AE35-0AA0 is a replacement IPD (Interface and Protection) card for the liquid-cooled Active Line Module in the SINAMICS S120 drive family. It handles 490 A at 380-480 V three-phase AC, 50/60 Hz, supporting a 300 kW module. This card manages the line-side interface, protection, and communication for the active infeed section of a liquid-cooled drive system. Because this is a spare part for a liquid-cooled module, it is not a standalone drive — it fits inside an existing Active Line Module enclosure. The card is classified as Product class C, meaning it is manufactured or produced to order and cannot be reused or returned for credit.
RoHS compliance started on 01-07-17. We source this through our distribution network and can quote it against an RFQ. No direct pin-compatible alternative is listed by Siemens for this specific IPD card — if you need a cross, we can check the SINAMICS S120 spare parts catalog during the quoting process.
Deployment context and compliance
This card mounts inside a liquid-cooled SINAMICS S120 Active Line Module enclosure — it is not a DIN-rail or panel-mount component. The 490 A rating means it is sized for high-power line infeed sections, typically feeding a common DC bus for multiple motor modules in a drive system. The liquid cooling loop must be maintained for the module to operate within its thermal limits.
