Siemens SINAMICS G120X 200–240 V 22 kW Inverter Power Module
6SL3230 Series Frame Size F — AC Motor Drive Unit
The 6SL3230 prefix identifies Siemens SINAMICS G120X chassis-mount inverter modules in the 200–240 V class. Within that series, the 1YC321 position encodes the power class and frame size; the suffix distinguishes enclosure type and approval region. The seed unit is a 22 kW frame-size F module intended for installation inside a cabinet or protected enclosure rather than as a standalone IP rating.
| Spec | Value |
|---|---|
| Output current | 108 A |
| Compatible motor | AC motor |
| Input voltage | 200–240 V |
| Series | SINAMICS G120X |
| Mounting | Chassis mount |
| Encapsulation | Box |
| Operating temperature | 20°C ~ 45°C |
| Package | Box |
| ROHS | ROHS3 Compliant |

The module ships as a box unit and requires a separate control unit and operator panel (not included) to complete a functional drive system.
Operating Envelope and Compatibility
Thermal and Mechanical Constraints
The 20°C to 45°C operating range is typical for enclosed cabinet installations with limited airflow. When mounting, ensure adequate clearance around the chassis to maintain airflow; do not mount directly above heat-generating components without thermal analysis. Chassis-mount form factor places the unit on a back-plate or DIN rail with dedicated fixing points defined by the frame-size F geometry.
System Integration Points
The unit is purpose-built for the G120X series and is not directly interchangeable with G120C or standard G120 variants despite shared naming conventions. Required complementary components (control unit, line reactor, EMC filter) depend on the specific machine configuration and must be selected from the SINAMICS G120X accessories family. The module does not include integrated fieldbus; communication is handled via the separate control unit.
200–240 V 22 kW Family Comparison
All listed alternates share the same voltage class and series; only power rating, output current, and frame size differ.
| MPN | Power | Output Current | Similarity |
|---|---|---|---|
| 6SL32301YC321UB0 | 22 kW | 108 A | seed |
| 6SL32301YC321UP0 | 22 kW | 108 A | 1.0 |
| 6SL32301YC321UF0 | 22 kW | 108 A | 1.0 |
| 6SL32301YC320UB0 | 22 kW | 108 A | 1.0 |
| 6SL32301YC320UP0 | 22 kW | 108 A | 1.0 |
| 6SL32301YC320UF0 | 22 kW | 108 A | 1.0 |
| 6SL32301YC301UB0 | 18.5 kW | 92 A | 1.0 |
| 6SL32301YC361UB0 | 37 kW | 176 A | 1.0 |
| 6SL32301YC381UB0 | 45 kW | 208 A | 1.0 |
The alternates share identical specs in encapsulation, series, mount type, and temperature rating. The 18.5 kW unit (6SL32301YC301UB0) fits smaller motor ratings; the 37 kW and 45 kW units (6SL32301YC361UB0, 6SL32301YC381UB0) require larger frame sizes and are physically distinct from the seed. The suffix variation among the 22 kW alternates (UB0 / UP0 / UF0) indicates market-specific certifications; qualification for a given region must be confirmed before procurement.
Engineering Verification Checklist
- Verify cabinet thermal management maintains ambient ≤ 45°C at module location
- Confirm AC motor nameplate current ≤ 108 A continuous rating
- Check input voltage range at point of installation (200–240 V ± 10%)
- Validate frame-size F mounting dimensions against cabinet or back-plate cutout
- Confirm control unit model selected is compatible with G120X power modules
- Verify DC link components (brake chopper, line reactor) sizing for 22 kW class
- Review EMC filter selection for target machine environment
- Verify grounding path meets Siemens chassis-mount torque and conductor specifications
- Confirm suffix code (UB0 / UP0 / UF0) matches intended market certification requirements
