The Siemens 6SL3352-3AG32-6AA0 is a replacement IPD (Interface and Protection) card for the SINAMICS S120 air-cooled Motor Module family, rated for 500-690V and 250kW. This is a spare part, not a standalone drive — it goes inside the Motor Module to handle gate-drive isolation, DC-link voltage sensing, and fault detection. The product class C designation means it is manufactured or produced to order, so it is not a stocked shelf item; each unit is built against a specific order.
RoHS compliance applies since 01-07-17. For marine or offshore installations, verify that the SINAMICS S120 platform carries the required class society type approval for your specific vessel class — the IPD card itself is a subassembly and inherits the Motor Module's certification status.
Integration Context
This card mounts inside the air-cooled SINAMICS S120 Motor Module frame, which is part of the larger S120 drive system — typically installed in a cabinet with a line-side Active Interface Module or Smart Line Module and a Control Unit. The 500-690V rating suits it for 690V marine or industrial networks common in vessel power systems and heavy industrial plants. The IPD card handles the isolation and protection interface between the Control Unit and the power stage; a fault on this card will trip the Motor Module offline, so keeping a spare on hand for a critical drive is standard MRO practice.
