The 6SL3230-3YE48-1UF0 is the F-suffix no-panel variant of the 132 kW G120X with 3C3 conformal coating and unfiltered EMC classification. At 338 A in FSF frame, it delivers the core environmental specification — corrosive atmosphere protection — without an integrated EMC filter or a local operator panel.

Unfiltered + 3C3 — the pragmatic 132 kW specification

The unfiltered (U) designation is the right call when the installation already includes external harmonic mitigation at the switchboard or facility level. In a pumping station with a dedicated transformer and line reactors on the main supply, adding an integrated EMC filter to each drive is redundant — the external equipment already handles harmonic management. The 3C3 coating addresses a separate concern: long-term corrosion protection for the drive's PCBs in wastewater or coastal atmospheres. Together, they specify a drive that is environmentally hardened without paying for an integrated filter the installation does not need.

FSF — the mid-size G120X frame

The FSF frame (305 × 709 × 360 mm) sits between FSE and FSG in the G120X lineup. At 132 kW, it handles pumps and fans that are substantial process loads without reaching the scale that demands the larger FSG frame. The 110% overload for 60 seconds provides start-up headroom for centrifugal loads with moderate inertia.
