Siemens SINAMICS G120X 110kW Variable Frequency Drive
G120X 6SL32303YE460UF0 Family Position
The 6SL32303YE460 series belongs to the Siemens SINAMICS G120X chassis-mount inverter family, designed for variable-speed AC motor control in industrial applications. The trailing "UF0" suffix designates frame size and filter class (Unfiltered variant); MPNs with "AF0/AB0/AP0" suffixes indicate filtered versions, while "YExxx1" variants indicate alternate power ratings within the same 277A current class.

Thermal and Installation Constraints
The 20°C–45°C operating range reflects forced-air or cabinet cooling requirements at full load. Panel builders must account for enclosure thermal management given the 277A continuous current and chassis-mount form factor—no integral heatsink is specified, implying external thermal management is required.
Compliance and Form Factor
IP20 rating aligns with the chassis-mount package style; the product ships in box packaging. Users specify this part when a discrete inverter module for cabinet mounting is required rather than an integrated compact drive.
