Siemens 6SL3210-1SE31-5UA0 SINAMICS S120 PM340 75 kW Power Module
An FSF PM340 power module rated at 75 kW and 145 A, without an integrated line filter.
Product Identification
6SL3210-1SE31-5UA0 is a Siemens SINAMICS S120 PM340 blocksize power module for three-phase 380 to 480 V AC supplies. The FSF power stage provides 145 A rated output and 75 kW based on rated current.
This unfiltered model is configured without an integrated line filter. Its 115 A high-overload base current, braking circuit, mechanical format and cooling demand must match the installed drive.

Functions
- Provides the motor-side power conversion stage for a compatible modular SINAMICS S120 drive.
- Supports 145 A continuous rated output together with 188 A S6 current at 40% duty.
- Delivers up to 220 A maximum output current for the documented overload profile.
- Supports an external braking resistor through the PM340 DC-link and braking connections.
- Uses internal air cooling in the FSF mechanical assembly.
Applications
- Modular industrial drives requiring a 75 kW rated PM340 power stage.
- Machines designed around a 55 kW high-overload duty selection.
- Retrofit work where the cabinet accommodates the FSF assembly and 150 l/s airflow.
- Dynamic-braking applications using a correctly selected external resistor.
- Installations whose EMC design specifies the unfiltered UA0 variant.
Lifecycle
- Retain the full 6SL3210-1SE31-5UA0 article number because the suffix distinguishes the unfiltered filter construction.
- Record the 145 A current class, 75/55 kW duty ratings and connected motor before exchanging the module.
- Back up parameters held by the Control Unit and document the braking-resistor configuration.
- Verify current Siemens spare-part or migration handling before scheduling a shutdown replacement.
- Inspect terminals, cooling passages, protective devices and cabinet conditions during recommissioning.
