What this PM340 power module delivers
The Siemens 6SL3215-1SE31-1UA0 is a SINAMICS S120 PM340 Power Module in blocksize frame FSF, rated for 110 A continuous output at 55 kW from a 380-480 V 3AC supply. The liquid-cooled construction means the heat exchanger handles the thermal load — critical for high-duty-cycle applications where fan-cooled drives would derate or need oversized cabinets. Per the datasheet, this is a spare part listing, so confirm the exact firmware version and drive control unit compatibility before committing the BOM line.
Integration notes for the FSF frame
The FSF blocksize frame is a liquid-cooled format — the module requires a properly sized coolant loop with the correct flow rate and pressure drop per the SINAMICS S120 design-in manual. Mounting is on the standard backplate or sub-panel; the liquid connections (typically G 1/2 or G 3/4 depending on the specific heat-sink variant) must be plumbed before the power cables. The 110 A output stage drives motors up to 55 kW on a 400 V line; for a 480 V line, the effective power is higher, so check the motor nameplate and the drive's rated output current — the 110 A is the hard limit regardless of voltage.
