Siemens 6SL32203YH481UP0 — SINAMICS G120X Variable Frequency Drive Module
Overview
The 6SL32203YH481UP0 is a chassis-mount variable frequency drive (VFD) module from Siemens' SINAMICS G120X series, rated for 500–690 V three-phase operation and 132 kW AC motors at 195 A output. The IP20 ingress protection and chassis-mount form factor place this device in cabinet-level industrial drive installations, typically within motor control centers or dedicated drive enclosures where personnel access is restricted. The catalog entry lists an operating temperature window of 20°C to 45°C and RoHS3 compliance; the data source did not provide input voltage tolerance, switching frequency, braking transistor rating, fieldbus communication options, EMC filter status, or short-circuit current rating—all of which are required before specifying this part into a branch circuit or coordination study.

Ordering-Code / Family Context
The MPN prefix 6SL3220-3YH48 encodes the power/size class and voltage class of the G120X series (Siemens naming convention for SINAMICS power modules). The suffix UP0 distinguishes the variant (firmware, communication interface, or filter configuration); UP versus CP versus CB versus UB suffixes typically reflect different control unit integration or firmware release levels. The trailing digit often indicates ECO compliance or specific regional certifications. This draft captures the chassis-mount frame size indicated in the title (FSF, likely Frame Size F); verify frame dimensions, terminal layout, and cooling method against the official G120X hardware manual before mechanical layout.
Missing Information — Verification Required
Before committing to this part in a Bill of Materials or power system design, the following fields are absent from the supplied catalog data and must be confirmed against the Siemens datasheet and hardware manual:
- Input voltage tolerance / mains frequency range
- Switching frequency and selectable carrier ranges
- Braking transistor: included or external, peak current / voltage
- EMC compliance class (C1/C2/C3 filter present or optional)
- Fieldbus / communication interface (PROFINET, EtherNet/IP, USS, Modbus, or standalone)
- Short-circuit current rating (SCCR) and coordinated fuse/breaker requirements
- Ground fault protection characteristics
- Enclosure dimensions and weight for cabinet layout
Verification required: Electrical ratings — input voltage range, SCCR, and overload current profile — must not be assumed. Selection must not proceed on electrical ratings until verified against the official Siemens G120X hardware manual and equipment catalog for this frame size.
Integration and Installation Notes
The chassis-mount form factor requires mounting to a backplane, panel, or dedicated heatsink within a sealed cabinet. The IP20 rating limits placement to controlled environments (no direct spray or outdoor exposure). Thermal management is critical given the 132 kW power class; the stated operating window of 20°C–45°C implies the enclosing cabinet must provide adequate airflow or cabinet cooling. The 195 A output rating at 690 V corresponds to approximately 227 kVA; cable sizing, motor feeder protection, and motor branch coordination must be evaluated per applicable motor protection standards. The catalog data does not specify terminal torque ratings, recommended cable sizes, or grounding bar configuration; these must be drawn from the G120X installation manual for Frame Size F.
Similar Catalog Parts
The following variants share the same G120X series, voltage class, power rating, current output, and chassis-mount package. Differences are limited to the MPN suffix, which governs firmware version, control unit type, or certification region. All share the parameters in the table below.
| Primary Part | Alternate MPN | Current Output | Voltage | Power | Series | Similarity |
|---|---|---|---|---|---|---|
| 6SL32203YH481UP0 | 6SL32203YH481UF0 | 195 A | 500–690 V | 132 kW | SINAMICS | 1.0 |
| 6SL32203YH481UP0 | 6SL32203YH481UB0 | 195 A | 500–690 V | 132 kW | SINAMICS | 1.0 |
| 6SL32203YH481UP0 | 6SL32203YH481CP0 | 195 A | 500–690 V | 132 kW | SINAMICS | 1.0 |
Why they are similar: Each alternate shares the same Siemens SINAMICS G120X series, the same power class (132 kW), voltage window (500–690 V), output current (195 A), chassis-mount enclosure, and Box packaging designation. The catalog similarity score reflects identical electrical and mechanical parameters; the MPN suffix variation (UP0, UF0, UB0, CP0) encodes configuration differences not visible in the shared spec keys (firmware variant, control unit type, or regional certification). Whether these suffix differences affect interoperability with a specific control system or require different engineering tools must be confirmed in the G120X catalog. No alternate listed here has been evaluated for functional equivalence in a specific application.
Similarity scores indicate catalog-level parameter match only; they do not constitute a quality comparison or substitution guarantee.
Selection and Substitution Guidance
All listed alternates match on output current, voltage, power, and mounting type. Substitution decisions must account for the suffix code meaning (firmware version, communication interface, or certification) which is not expressed in the supplied spec fields. When specifying a G120X module, confirm that the suffix variant aligns with the target control unit, firmware revision required for the application, and applicable regional certifications (e.g., UL, CE, CCC). Consult the Siemens ordering guide for the G120X series to decode suffix meanings before procurement.
FAQ
Q: What voltage range does the 6SL32203YH481UP0 support? A: The title indicates 500 V to 690 V three-phase operation, consistent with the 132 kW power class. The data source did not provide input voltage tolerance or acceptable mains frequency; verify against the G120X hardware manual before installation.
Q: What is the difference between the 6SL32203YH481UP0 and the 6SL32203YH480UP0? A: Both carry the same title, power rating (132 kW), voltage (500–690 V), and output current (195 A). The "481" versus "480" prefix difference encodes a variant distinction not explained in the supplied fields. Confirm whether the suffix and prefix combination corresponds to firmware, control unit type, or certification using the official Siemens G120X ordering code guide.
Q: Does the 6SL32203YH481UP0 include a built-in EMC filter or braking transistor? A: The supplied catalog data does not specify EMC filter class or braking transistor inclusion. These are critical for motor stopping performance and electromagnetic compatibility in the installation. Verify filter type and braking options in the G120X hardware manual for Frame Size F.
