Siemens 6SL3210-1PE28-8UL0 SINAMICS G120 PM240-2 Power Module
A 380–480 V power module rated at 45 kW low-overload duty and 37 kW high-overload duty for modular SINAMICS G120 drive systems.
Overview
6SL3210-1PE28-8UL0 is an unfiltered SINAMICS G120 PM240-2 Power Module in frame size FSE. It provides the power stage for a modular G120 drive and includes an integrated braking chopper for applications that require a connected braking resistor.
The article is designed for three-phase 380 to 480 V supplies. Its unfiltered configuration is intended for projects in which the system designer manages the required EMC measures at machine or cabinet level.

Features
- Integrated braking chopper supports dynamic braking when a correctly sized external braking resistor is engineered into the installation.
- The modular G120 architecture allows the PM240-2 power stage to be paired with a compatible Control Unit selected for the required communication and control functions.
- The documented 4 kHz pulse frequency and separate low- and high-overload ratings help engineers match the module to the motor duty profile.
- Internal forced-air cooling is specified for the FSE enclosure, so cabinet airflow and clearance remain part of the thermal design.
- The unfiltered suffix distinguishes this article from filtered variants that have different EMC characteristics and order numbers.
Applications
- Industrial pumps, fans, conveyors and process machinery requiring a 37–45 kW modular variable-speed drive stage.
- Machines with regenerative deceleration energy handled through an external braking resistor and the integrated chopper.
- Control cabinets where EMC filtering is provided as part of the overall installation design.
- SINAMICS G120 systems that need a replaceable power stage separate from the Control Unit and operator panel.
Lifecycle
- Record the complete 6SL3210-1PE28-8UL0 article number because filtered and unfiltered PM240-2 variants are not equivalent ordering selections.
- Before replacement, compare supply voltage, overload duty, motor current, frame size, cooling path and braking-resistor design.
- The Control Unit and operator panel are separate system components and must be checked for firmware and application compatibility.
- Retain the drive parameter set and motor data before maintenance so the replacement power stage can be commissioned against the installed machine.
FAQ
Is 6SL3210-1PE28-8UL0 supplied with an EMC filter?
No. 6SL3210-1PE28-8UL0 is the unfiltered PM240-2 version, so the project must provide the required EMC solution.
What power ratings apply to 6SL3210-1PE28-8UL0?
The official ratings are 45 kW for low-overload duty and 37 kW for high-overload duty.
Does 6SL3210-1PE28-8UL0 include a braking chopper?
Yes. The braking chopper is integrated; the external braking resistor must still be selected and installed correctly.
Which frame size is used by 6SL3210-1PE28-8UL0?
It uses frame size FSE with dimensions of 551 × 275 × 237 mm.
Can 6SL3210-1PE28-8UL0 operate without a Control Unit?
No. It is the power module in a modular G120 system and requires a compatible SINAMICS Control Unit.
What should be checked before ordering 6SL3210-1PE28-8UL0?
Confirm the full suffix, 380–480 V supply, overload class, motor current, unfiltered EMC plan, cabinet cooling and braking requirements.
