Siemens SINAMICS G120X Series — Chassis-Mount AC Drive, 200–240 V, 4 kW
G120X 6SL32301YC200UB0 vs. In-Catalog Variants
The following comparison is based on manufacturer-listed specifications. Confirm that any cited alternate meets the application's mechanical, thermal, and regulatory requirements before use.

All six parts share the same output current, input voltage range, power rating, AC motor type, chassis-mount form factor, and temperature window. The only distinguishing identifier is the four-character suffix trailing the common prefix 6SL32301YC2. Each suffix follows Siemens' packaging or firmware revision code; no functional specification difference appears in the record.
Why the others are similar: The entire set shares the G120X series platform, SINAMICS firmware lineage, and identical electrical ratings. The suffixes (UB0, UP0, UF0, U1B0, U1F0, U1P0) encode variant codes that are internal to Siemens' ordering system and do not appear as separate spec fields. Confirm with the Siemens sales office whether a specific suffix corresponds to a required certification, firmware version, or mechanical packaging option before substituting.
Higher-Power Alternates in SINAMICS G120X Catalog
| MPN | Output Current | Power | Series |
|---|---|---|---|
| 6SL32301YC260UB0 | 57 A | 11 kW | SINAMICS G120X |
| 6SL32301YC280UB0 | 73 A | 15 kW | SINAMICS |
These units serve the same 200–240 V chassis-mount G120X platform at increased power and current. They are not drop-in electrically equivalent to the seed and require separate mechanical clearance, thermal management, and branch-circuit protective device sizing.
Engineering Verification Checklist
- Confirm the drive's output current rating (23.7 A) accommodates the connected motor's full-load current plus any transient margin.
- Verify chassis mounting orientation and minimum clearance per the SINAMICS G120X hardware manual for the FSB frame size.
- Ensure the 20°C–45°C operating temperature range is compatible with the enclosure's worst-case ambient condition, considering internal heat load from the drive.
- Validate that the 200–240 V input range matches the available supply; no auto-ranging is indicated in the record.
- Check that AC motor type (induction, fixed frequency) aligns with the G120X's control mode capability for the application.
- Confirm ROHS3 status satisfies the target market's substance restrictions.
- Review whether the suffix variant (UB0 vs. UP0/UF0/U1x) carries a required firmware revision or certification for the installation jurisdiction.
- Specify the appropriate field-installed line reactor, DC-link choke, or EMC filter if the installation's conducted emissions or supply harmonic limits require it.
- Coordinate protection coordination with the upstream short-circuit protective device to ensure the drive's internal IGBT fault clearing capability is not exceeded.
