Siemens SINAMICS G120X Power Module (6SL32301YC260UF0)

6SL32301YC260UF0 Electrical and Mechanical Ratings

The designation breaks down as follows: the YC26 prefix identifies this as a 200–240 V AC unit, the 0 before the suffix indicates frame size FSD, and the UF0 suffix codes the base device variant (U = basic device; F = 50 Hz input; 0 = no integrated filter; no additional options). All SINAMICS G120X power modules in the 11 kW / 57 A class share this mechanical envelope.

G120X System Integration

The G120X series separates power electronics from control intelligence. The power module (this part) handles the inverter stage and DC link management; a matched control unit (ordered separately) provides the application logic and fieldbus interface. The two modules interconnect via the standard G120X internal bus.

This chassis-mount module ships as a standalone box unit. Panel builders typically install it in a dedicated enclosure with appropriate ventilation; the 45 °C upper operating limit applies to free-air conditions—thermal management inside a cabinet may require derating or forced airflow.

Graded Alternatives Within SINAMICS G120X Family

All nine part numbers belong to the SINAMICS G120X family; the 11 kW variants share the FSD frame and 57 A output rating. The suffix differences (UB0, UP0, UF0, UF1, etc.) encode option variants such as integrated chokes, specific firmware configurations, or build standards—review the option code definitions in the G120X hardware manual to confirm fit for a given application. The lower-rated options (FSA through FSC) use smaller frames and lower current ratings; they are not direct drop-in alternatives for the 11 kW chassis.
