Siemens 6SL32301YH520CB0 — SINAMICS G120X Variable Frequency Drive, IP20, 500–690 V, 200 kW
Overview
Before proceeding with any selection note, the following critical electrical ratings are not present in the supplied catalog fields: load voltage range (though 500–690 V appears in the title), continuous input current, power dissipation, EMC environment class (C1/C2/C3 indicated only by suffix in title), and overload capability. The datasheet must be consulted for those values. What the catalog does confirm is a Siemens SINAMICS G120X frame size C (FSG), chassis-mount (IP20), driving AC motors at up to 281 A output, within a 20 °C to 45 °C ambient window.
This part belongs to the Siemens SINAMICS family of low-voltage AC drives. The G120X series targets heavy pump, fan, and compressor applications in industrial environments. The 6SL3230 prefix is the standard Siemens ordering code for G120X power modules; the digit block after 1YH encodes the voltage class, power rating, and frame size. A trailing C3 suffix in the catalog title suggests compliance class (C3 per EN 61800-3), which permits use in the second environment without additional filtering in many jurisdictions—verify against the target installation's EMC requirements.

Verification required before selection
- Load voltage range: Title specifies 500–690 V nominal; the specs block does not contain a voltage field. Confirm the DC-link voltage and switching frequency limits.
- Power rating: Title indicates 200 kW; specs block does not list wattage. Verify motor shaft power capability at the target voltage and switching frequency.
- Input current and supply requirements: Not in specs. Branch-circuit coordination requires the input current draw and any line-side harmonic mitigation.
- EMC class: Title suffix "C3" implies EN 61800-3 Category C3 (industrial environment, restricted distribution). If the installation is residential or light-commercial, a C2 or C1 unit may be required; verify the suffix meaning for this specific frame.
- Overload and ramp ratings: Catalog does not list 100 % overload duration or ramp time limits. Essential for pump/fan sizing.
- Communication / fieldbus: No protocol field present (PROFINET, Modbus TCP, etc.); confirm separately if required.
- Protective rating (IP20): Title confirms IP20. Confirm that the chassis-mount form factor is acceptable for the target enclosure; no additional sealing is provided.
Integration Notes
The chassis-mount IP20 designation means the unit is designed for installation inside a parent enclosure that provides the final environmental protection. Physical mounting dimensions, airflow clearance, and any required external line reactors or filters are not specified in the supplied fields; these must come from the G120X hardware manual for the FSG frame. Cabling to the motor, DC bus, and control terminals requires cable-size and torque specifications from the datasheet, not from catalog fields.
Similar Catalog Parts
The similarity search returned multiple G120X units with identical series, mounting, and motor type. The top three by similarity are listed below.

Why they are similar
All four share identical output current (281 A), motor type, mounting, encapsulation, temperature range, series, and ROHS status, differing only in the numeric block between the 6SL32301YH5xx prefix and the trailing frame/suffix codes. The CF0 and CP0 variants carry the same power class but lack "C3" in their catalog titles; whether this reflects a certification difference or merely ingestion variation is not stated in the supplied data—confirm with the Siemens ordering guide.
Lower-similarity alternates in the result set include the 160 kW unit (6SL32301YH500CB0, 231 A) and the 250 kW unit (6SL32301YH540CB0/C P0, 338 A), which share the same chassis-mount SINAMICS G120X platform but differ in current rating and power class.
FAQ
What does the C3 suffix in the title of 6SL32301YH520CB0 mean? The catalog title indicates "C3", which in Siemens SINAMICS ordering conventions corresponds to EMC environment class C3 (EN 61800-3, industrial environment, unrestricted distribution). The specs block does not contain an explicit EMC field; verify the suffix definition against the official Siemens G120X ordering guide before specifying for regulatory compliance.
Can 6SL32301YH520CB0 drive a motor rated at 200 kW on a 400 V supply? The catalog title specifies 500–690 V nominal; it is unclear whether this unit can operate on a 400 V supply. The output current of 281 A and the 200 kW rating in the title are consistent with mid-voltage (500–690 V) operation. Confirm the usable voltage window and derating curves from the G120X hardware manual before specifying.
Is the operating temperature range of 20 °C to 45 °C the full ambient range or a derated window? The catalog lists 20 °C to 45 °C under operating temperature. Whether this is a continuous full-load rating or a derated window (e.g., full output to 45 °C with reduced output above a lower temperature) is not explained in the supplied fields. The G120X hardware manual provides derating tables for altitude and temperature.
