What this module is
The 6SL3320-1TH38-1AA0 is a SINAMICS S120 Single Motor Module — the power stage that drives one motor from a common DC bus. It takes a DC input of 890 to 1035 V and delivers a three-phase AC output from 0 to 690 V at 810 A, rated for 800 kW continuous load.
What the ratings mean for fit
The 810 A output at 690 V AC means this module handles a 800 kW induction or synchronous motor directly from the DC link of an active infeed or line module. The DC input range of 890 to 1035 V matches the standard SINAMICS S120 DC-link voltage from a 400 V or 690 V AC supply after rectification. The IP00 chassis unit requires enclosure mounting — it's not a standalone drive, it lives inside a cabinet with forced air cooling provided by the internal fan. The Drive-CLiQ cable is included, so the module connects directly to a Control Unit or another Drive-CLiQ node without a separate cable order. This saves a line item on the BOM and one potential point of failure in the cabinet.
