The 6SL32202YE400AB0 carries a suffix "AB0" identifying the FSE (Factory Set Environment) configuration and IP20 chassis form. Siemens G120X modules are typically deployed as drive inverter stages in water, wastewater, and HVAC pumping applications where the 55 kW class handles mid-range centrifugal compressor or pump motor loads.
Parameter fidelity across G120X 55 kW family
All 9 records share identical electrical parameters: 149 A output, 380–480 V input, 55 kW. Differences appear only in the trailing alpha-numeric suffix of the full MPN (position 13–14), which encodes the approval region, firmware version, or environmental package rather than core power-stage performance.
This uniformity means any chassis-mount 6SL32202YE400AB0 variant should be evaluated by its suffix designation against the target installation's certification requirements rather than by output capability.
Comparison: 6SL32202YE400AB0 vs. G120X family peers

All listed G120X modules share the same electrical specification. Qualified comparison requires consulting Siemens configuration tools or the device's ordering documentation to determine which suffix aligns with the target market's certification and firmware requirements.
- 6SL32202YE400AP0 shares AB0's FSE firmware baseline with a suffix variance suggesting an alternate regional approval or packaging variant.
- 6SL32202YE400AF0 mirrors AP0 in electrical rating; the trailing "F0" suffix points to a different configuration code in the same series.
- 6SL32202YE401AB0 increments the type code in position 12, likely representing a minor hardware revision within the same power class.
Engineering verification checklist
- Confirm chassis mounting dimensions and flange rating match cabinet cutout specifications
- Verify input voltage range matches upstream protection and transformer taps (380–480 V AC)
- Confirm output current rating (149 A) suits motor nameplate full-load amperage with derating for ambient temperature above 40°C
- Check that enclosure IP20 rating is adequate for the installed environment; upgrade to a higher-rated enclosure if needed
- Validate that the FSE suffix configuration supports the intended control interface (USS, Modbus RTU, or PROFINET as required)
- Confirm ground-fault protection and short-circuit coordination matches upstream breaker rating
- Verify DC link busbar sizing and terminal torque specifications for 149 A continuous current
- Check that operating temperature derating curve (20–45°C) covers worst-case cabinet ambient
- Confirm EMC filter and line reactor requirements for the installation's conducted emission limits
