Plants that already own their EMC strategy do not need the drive to bring a filter — and the 1UP0 build of this 132 kW SINAMICS G120X respects that: the U-suffix ships the power stage unfiltered, leaving the radio-interference suppression to the external hardware the site has standardised on, while PROFIBUS DP stays onboard and the DC terminals stand ready for the du/dt filter.

When is the unfiltered build the right order number?

When the installation already provides the filtering — central line filters in the incomer cabinet, or site-wide EMC measures that make a per-drive filter redundant. Buying an integrated C2 or C3 filter into every drive then means paying twice for suppression; the U-suffix build skips it, and the EMC category is set by the external hardware instead. For greenfield cabinets without any filter infrastructure, the C2- or C3-filtered builds of the same 132 kW frame are the self-contained choice.

What does the 132 kW tier deliver around the missing filter?

The full power stage: 256 A rated in LO duty (132 kW continuous, 110% per 60 s) against the 338 A maximum, 110 kW in HO duty, and the DC link terminals for the du/dt filter on long motor cable runs — the same provision the filtered builds carry. The FSF housing measures 305 x 709 x 360 mm, sharing its frame class with every 132 kW build and sitting 290 mm shorter than the 160 kW FSG units.
