Siemens 6SL32303YH540CB0 — SINAMICS G120X 250 kW AC Drive Module
The primary part number 6SL32303YH540CB0 belongs to the Siemens SINAMICS G120X series. The MPN prefix 6SL3230 denotes the SINAMICS frame; the character positions encode the voltage class (H = 500–690 V AC), power rating (250 kW), and output current class (338 A). The suffix CB0 indicates the firmware variant and revision level. All G120X units in this group are chassis-mount, box-encapsulated, AC motor drive modules designated Active with ROHS3 Compliant status.
Engineering Verification Checklist
- Confirm supply voltage range at installation site matches 500–690 V AC
- Verify motor nameplate current does not exceed 338 A continuous output rating
- Verify ambient temperature at the drive location stays within 20°C to 45°C
- Confirm chassis mounting provisions and enclosure IP20 rating match cabinet design
- Check that the driven motor is a three-phase AC motor compatible with G120X drive architecture
- Confirm integration with existing SINAMICS G120X system components (CU, PM)
- Verify all auxiliary power and control connections match system schematics
- Confirm ROHS3 Compliant status aligns with end-installation environmental requirements

System Integration Notes
The 6SL32303YH540CB0 is designed for use with the broader G120X series ecosystem. It must be paired with the appropriate Control Unit (CU) and Power Module (PM) to form a functional drive system. Chassis mounting requires adequate clearance per the drive's thermal management design. The IP20 rating limits the drive to indoor enclosures without protection against direct water ingress.
Catalog Comparison (In-Catalog Screening Only)
The table below presents side-by-side spec data for the primary part and any catalog alternates sharing identical parameter keys. All entries require the reader's own engineering qualification; this is not a recommendation for interchange.

The primary part 6SL32303YH540CB0, along with the six variants bearing the 540CB0 / 540CF0 / 540CP0 / 541CB0 / 541CF0 / 541CP0 suffixes, share identical electrical ratings (338 A output, 250 kW, 500–690 V) and thermal limits. The suffixes CB, CF, CP indicate firmware/escape variants; the differences do not alter the current or power ratings.
The three alternates 6SL32303YH500CB0, 6SL32303YH520CB0, and 6SL32303YH520CP0 use the same 500–690 V class and G120X architecture but are rated for lower power classes: 160 kW / 231 A and 200 kW / 281 A respectively.
FAQ
What motor types are compatible with the 6SL32303YH540CB0? The drive is designed for three-phase AC motors. The exact motor construction and encoder requirements depend on the application closed-loop strategy and the paired Control Unit configuration.
What distinguishes the CB, CF, and CP suffix variants? The suffix encodes the firmware/escape release. All three variants in the primary group share the same output current (338 A) and power rating (250 kW). Selection depends on system-level firmware compatibility with the installed Control Unit.
Can the 6SL32303YH540CB0 be used in a 400 V installation? The unit is classified for 500–690 V AC systems. Operation outside this range is not indicated in the catalog records; the appropriate SINAMICS G120X variant for lower voltages must be selected separately.
