Siemens G120X SINAMICS 500–690 V Chassis Drive Modules

6SL32303YH201AB0 core specifications

The part is a G120X frame size D (FSD) inverter module rated for 4 kW at the cited voltage window. The operating temperature range reflects derating behavior under load rather than absolute survival limits; thermal management and cabinet airflow must be evaluated for the specific installation.

Functional positioning

The SINAMICS G120X series targets pump, fan, and compressor applications in the heavy industrial segment where medium-voltage AC drive support is required. Chassis mounting implies panel or enclosure installation with external heat sinking or forced-air cooling; the 20–45 °C ambient window constrains cabinet thermal design in enclosed motor-control rooms or plant floors without dedicated cooling. The UF suffix variants in the alternates differ in firmware/factory configuration for universal field (UF) control, while the C2 variants refer to a specific category of built-in filter or drive classification.

Comparable Siemens G120X FSD modules

All listed alternates share 9 A output, 500–690 V AC input, 4 kW rating, chassis mount, and SINAMICS series designation. The reader must qualify each variant independently for firmware type, filter class, and order-specific configuration.

C2 and UF variants share the same electrical ratings but differ in integrated filter and control firmware. The MPN prefix difference between YH201 and YH200 reflects minor variant coding that does not change the fundamental power or current rating.
