Siemens 6SL32203YC400UP0 — SINAMICS G120X AC Drive Module
Parametric Comparison: UP0 / UB0 / UF0 / UP1 Suffix Variants
All six G120X options at this power class share identical electrical, mechanical, and environmental specifications. The trailing suffix encodes firmware/configuration variants, not performance grades.
| Spec | 6SL32203YC400UP0 | 6SL32203YC400UB0 | 6SL32203YC400UF0 | 6SL32203YC401UP0 |

Readers must qualify suitability for their specific control architecture and motor characteristics independently; parametric tables alone do not establish interchangeability for a given installation.
- UP0 / UP1: Same base firmware; suffix difference reflects configuration or firmware release window. UP1 carries a slightly higher similarity index in catalog indexing (0.94 vs 0.88 edit distance), but both share identical rated current and power specs.
- UB0 / UF0: Alternative configuration variants within the same hardware family; output current and voltage ratings are indistinguishable from UP0/UP1.
Core Specifications: G120X 55 kW Chassis Module
- Input voltage: 200..240 V AC
- Output current: 260 A

The 260 A output rating at 200–240 V single-phase (or derived three-phase) places this unit in the upper end of the G120X chassis lineup. Thermal management during sustained high-load operation requires adequate enclosure ventilation or cabinet-level cooling per Siemens thermal guidance for the FSF frame designation.
Family Positioning: SINAMICS G120X Chassis Range
The Siemens G120X series covers a broad power spectrum within the same mechanical form factor. The seed unit at 55 kW / 260 A sits well above the FSB/FSC entries and the 18.5 kW (92 A) mid-range variant. Frame size letters (FSA through FSF) correlate with current and thermal handling; frame-matching in panel design avoids thermal derating issues.
All G120X variants are ROHS3 compliant and share the same operating temperature window (20°C–45°C) and chassis-mount form factor.
