The SINAMICS G120X 6SL3230-3YE26-1UB0 is an 11 kW frequency converter in the FSC frame, configured with DC terminals, an unfiltered output stage, and an IOP-2 operator panel. It is designed for pump, fan, and compressor applications in water/wastewater, building technology, and HVAC sectors. It delivers 35 A at 380–480 V 3 AC with 110% overload for 60 seconds.

What does the 1UB0 suffix configuration include?

The suffix 1UB0 decodes as: DC terminals present (1), unfiltered output with no integrated EMC filter (U), and full-feature configuration with IOP-2 graphical operator panel (B). The DC terminals enable direct connection of a du/dt filter for motor winding protection on long cable runs. The unfiltered output means external EMC measures must be applied where conducted emissions compliance is required. The IOP-2 panel provides a local graphical interface for commissioning, parameterization, and diagnostics at the drive.

How does the 11 kW FSC frame compare to other G120X power ratings?

The FSC frame (140 × 295 × 209 mm) houses both the 11 kW and 15 kW power ratings in identical external dimensions. At 35 A output, the 11 kW variant fills the gap between 7.5 kW and 15 kW — a useful option when 15 kW is more power than the application requires but 7.5 kW is marginal. The 110%/60 s overload profile is consistent across all G120X power ratings.
