The Siemens 6SL3357-3AE41-4AA0 is a replacement IPD (Interface and Protection) card purpose-built for the SINAMICS S120 liquid-cooled Active Line Module rated at 900 kW on a 380-480 V three-phase supply, 50/60 Hz, pulling 1405 A. This is a spare part — not a standalone drive — so it slots into the existing Active Line Module chassis to restore communication, protection, and interface functions when the original card fails. The 1405 A rating ties directly to the module's full-load current; if your line-side module is spec'd at that current, this card is the correct drop-in replacement.
Compliance and shipping documentation
RoHS compliant since April 1, 2018, and carries a REACH Article 33 duty-to-inform declaration for lead (CAS 7439-92-1) above 0.1% w/w — standard for power electronics with soldered joints. The group code is R2SC and product group is 4Q30 — these are Siemens internal cataloging fields that help with cross-referencing in their ordering system but do not affect fit or function.
