Siemens 6SL3220-1YD30-0UB0 SINAMICS G120XA converter

Documented Siemens SINAMICS G120XA converter with a 18.5 kW low-overload rating; verify installation fit before replacement.

Documented converter identity

Rebuilt from individual evidence

Siemens lists 6SL3220-1YD30-0UB0 as a SINAMICS G120XA converter and assigns it a low-overload rating of 18.5 kW.

The manufacturer declaration records an unfiltered (UF) configuration, IP20 protection, and USS fieldbus for this exact part code.

Inferred system position: the converter sits between a three-phase AC supply and a connected motor load in an industrial drive system.

Unknown: installation fit, motor sizing, wiring, firmware, physical condition, and current availability require separate confirmation.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Converts three-phase AC into controlled electrical output for a connected motor drive.
System position: Sits between the three-phase supply and a connected motor load in the machine drive path.
Upstream / inputs: Receives the three-phase supply that feeds this converter in the motor-drive path.
Downstream / outputs: Sends controlled electrical output toward the connected motor load.
Limitations: Unknown: installation fit, motor sizing, wiring, firmware, physical condition, and current availability require separate confirmation.

Inferences

The converter sits between a three-phase AC supply and a connected motor load in an industrial drive system.
Confidence: medium
Rationale: The manufacturer calls the exact item a G120XA converter and assigns it a motor-drive rating; the machine-side placement is therefore an explicit system inference, not a claimed wiring diagram.
