Siemens 6SL32203YE320UF0 — SINAMICS G120X Chassis-Mount AC Motor Driver
The Siemens 6SL32203YE320UF0 is a chassis-mount variable frequency drive in the SINAMICS G120X series, rated for 22 kW AC motors at 380–480 V with a 61 A output. This IP20 unit ships in box packaging and carries ROHS3 Compliant status. It is suited for installation in motor branch enclosures where active cooling and a controlled environment (20°C to 45°C) are available.
Catalog Comparison: Primary Unit and In-Catalog Variants
The following table presents the primary part alongside three in-catalog variants sharing identical core electrical and mechanical parameters. All four parts are Siemens G120X drives; suffix differences reflect variant coding for control electronics, filtering, or braking options.

Why the variants are listed together
The three alternates carry the same 6SL32203YE32x base code and differ only in the final suffix (UB0, UP0, AF0). Matching spec keys across the seed and each alternate include output current, motor power, supply voltage, motor type, mounting type, encapsulation, and series — yielding the maximum catalog similarity score of 1.0 for all three. The UB0 and UP0 suffixes denote different control or filtering configurations that do not alter the power stage ratings. The AF0 suffix identifies a control electronics variant within the same G120X family; one record reflects "Series": "SINAMICS G120X" rather than "SINAMICS" alone, but the underlying power electronics remain identical.

Motor Branch Integration Context
The 6SL32203YE320UF0 operates as the power conversion stage in an AC motor drive train. In a typical panel layout, chassis-mount drives are secured to a back-plate or sub-panel inside an enclosure sized for the ambient temperature range of 20°C–45°C. The IP20 rating indicates the unit is protected against solid objects larger than 12.5 mm but lacks protection against water; enclosure selection must account for this in environments with condensation risk or splash exposure.
Output current of 61 A at 380–480 V defines the branch conductor sizing and any upstream short-circuit protection coordination. The 22 kW rating anchors the drive in the lower-mid power band of the G120X family, placing it between compact single-module units and higher-power modular configurations that may use external DC link components. Panel builders integrating this drive should confirm that the motor nameplate current falls within the drive's continuous rating or is managed through appropriate sizing margin and thermal consideration.
In-Catalog Variant Overview
Four additional parts share the same electrical and mechanical specs with this primary unit and are included for completeness. The suffix differences among UB0, UP0, AF0, AB0, AP0, UF0, and UP0 variants represent G120X ordering code distinctions for control interface options, filter inclusion, or braking chopper configuration. The 6SL32203YE321x variants carry a 21x suffix indicating a different power-stage configuration variant within the same family; their output current and voltage ratings remain identical to the seed.
All listed parts are Active status and ROHS3 Compliant per the catalog records. The reader's own qualification process should confirm that the control electronics variant suits the target application architecture (PLC interface, safety function integration, or braking requirements).
