The 1AB0 build of this 132 kW SINAMICS G120X packs the complete filtered-serial specification into the shortest frame of the large-power range: C2 filter integrated, DC terminals for du/dt filters, BACnet MS/TP and Modbus RTU onboard — 256 A rated in LO duty, 110 kW in HO, all in 305 x 709 x 360 mm.

Where does the HO rating of this tier actually get used?

On the constant-torque sections — hoists, loaded start-stop conveyors, mixers — where the load does not fall off with speed. The 132 kW LO rating covers the pump and fan duty, but the 110 kW HO rating (150% for 60 s in a 600 s cycle) is what carries a section that starts loaded and stays loaded, and the 338 A maximum behind it defines the switchgear ceiling either way.

What does the C2 class plus the serial trio decide for the section?

The compliance story and the wiring story, both integrated. The C2 filter meets the shared-grid emission limits without an external stage; BACnet MS/TP and Modbus RTU cover the building and SCADA layers from the onboard port; and the DC terminals keep the du/dt option open for the motor runs that need it. If the grid turns out purely industrial, the C3- and unfiltered builds of the same 132 kW frame trade the filter class without moving any dimension.
