6SL3210-1SE31-0UA0 is a Siemens SINAMICS S120 PM340 power module for three-phase 380 to 480 V AC drive systems. It supplies 90 A rated output in a FSE blocksize assembly and is rated at 45 kW based on rated current.

This is the unfiltered version. The complete order number must be checked because the suffix changes the line-filter configuration while the current class determines overload capability, cabinet space and cooling demand.

• Rated output current: 90 A with 45 kW rated power.
• High-overload base current: 80 A with 37 kW power rating.
• S6 output current at 40% duty: 117 A; maximum output current: 150 A.
• Rated pulse frequency: 4 kHz; efficiency: 0.97.
• Documented power loss: 1.21 kW with 2 × 54.9 l/s cooling-air requirement.

• Pair 6SL3210-1SE31-0UA0 with a compatible SINAMICS Control Unit and motor selected for the documented current and overload profile.
• Provide the required external EMC components because this UA0 version has no integrated line filter.
• Engineer the external braking resistor at or above 15 Ω and keep its cable within 15 m.
• Dimension protection, conductors, grounding and cabinet ventilation for the 90 A FSE power stage.
• Restore and validate the drive parameter set through the Control Unit after power-module replacement.

• Modular industrial drives requiring a 45 kW PM340 rated-power stage.
• Machines using a 37 kW high-overload duty selection.
• Retrofit work where the existing cabinet matches the FSE mechanical and airflow requirements.
• Drive systems requiring dynamic braking with an externally selected resistor.
• Installations whose EMC design uses the unfiltered UA0 configuration.
