The Siemens 6SL3353-3AE41-0AR4 is a factory-authorized spare IPD (Interface and Protection Device) card for the SINAMICS S120 air-cooled Active Line Module. It handles 380-480 V AC three-phase at 50/60 Hz, rated for 985 A continuous with overload capability up to 200% reactive current. That 200% headroom matters when the drive needs to ride through a momentary line dip or supply reactive compensation during a heavy ramp — the card won't fold back before the module does. This is a C-class product: manufactured or produced to order, which means it's not a shelf-stocked spare. It cannot be reused or returned once installed. Plan your order lead time accordingly — this isn't something you pull from a bin for an emergency swap.
Listed lifecycle stage is mature, and the product status is Active. No end-of-life or phase-out notice is recorded on this order code. The part carries AL: N / ECCN: N export control classification, so it ships without special licensing for most destinations.
