The 132 kW tier sits in a different frame than its neighbours — and that is the first thing to notice about the 0AB0 build of this SINAMICS G120X: at 305 x 709 x 360 mm it is 290 mm shorter than the 160 and 200 kW FSG units, which makes it the rating that fits cabinets the others do not. The C2 filter class and the B-suffix serial trio (BACnet MS/TP, Modbus RTU, USS) come integrated.

Why does the 132 kW rating live in the FSF frame?

Because the power stage fits it. FSF runs from the mid-range up through 132 kW before the FSG frame takes over at 160 kW — so specifying 132 kW instead of 160 kW is not only a current decision (256 A LO against the 338 A ceiling) but a cabinet-height decision worth 290 mm. For switchrooms already near their height budget, that difference can decide the whole layout.

What does the C2 class plus the serial trio serve here?

The shared-grid building or utility room with a serial control layer: the C2 filter meets the tighter first-environment emission limits without external hardware, BACnet MS/TP reports to the building trunk, Modbus RTU to the SCADA table, and USS covers the bench. Ratings stay the family duty profile — 132 kW continuous in LO (110% for 60 s), 110 kW in HO — with no DC terminals to land in the lean layout.
