6SL3210-1SE31-1UA0 is a Siemens SINAMICS S120 PM340 blocksize power module for three-phase 380 to 480 V AC supplies. The FSF power stage provides 110 A rated output and 55 kW based on rated current.

This unfiltered model is configured without an integrated line filter. Its 95 A high-overload base current, braking circuit, mechanical format and cooling demand must match the installed drive.

• Provides the motor-side power conversion stage for a compatible modular SINAMICS S120 drive.
• Supports 110 A continuous rated output together with 143 A S6 current at 40% duty.
• Delivers up to 180 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.

• Pair 6SL3210-1SE31-1UA0 with a compatible SINAMICS Control Unit and a motor selected for the 110 A current class.
• Provide the external EMC measures required because the UA0 version does not contain an integrated line filter.
• Use an external braking resistor greater than 8.2 Ω and keep its connection within the documented 15 m limit.
• Dimension protection, conductors and grounding for the 115 A / 129 A input-current values.
• Provide the FSF cabinet space and 150 l/s cooling airflow required by the power stage.

• Retain the full 6SL3210-1SE31-1UA0 article number because the suffix distinguishes the unfiltered filter construction.
• Record the 110 A current class, 55/45 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.
