The 6SL3230-3YE48-1UB0 is a 132 kW SINAMICS G120X in FSF frame — one frame size below the FSG that houses the 160–250 kW variants. Delivering 338 A at 380–480 V, it is specified with 3C3 conformal coating for corrosive atmospheres, the IOP-2 operator panel for local access, and no integrated EMC filter (U classification).

132 kW in the FSF frame

The FSF frame (305 × 709 × 360 mm) is the step below FSG in the G120X's nine-frame-size lineup. At 132 kW and 338 A, this drive powers medium-to-large pump and fan loads — a secondary pump in a water distribution network, a cooling-tower fan, or a ventilation fan in a tunnel or parking structure. The overload rating at this power level is 110% for 60 seconds, reflecting the steady-state duty typical of centrifugal pumps and fans.

Unfiltered with 3C3 and IOP-2 — why this combination?

The U (unfiltered) EMC classification means the drive has no integrated EMC filter. This is specified when the installation provides external harmonic mitigation — a line reactor, an active front end, or a dedicated transformer with sufficient impedance — or when the supply network's harmonic limits are managed at the facility level rather than at the individual drive. The 3C3 coating protects the drive's internal electronics in wastewater or coastal environments; the IOP-2 provides local commissioning and diagnostic access. The unfiltered designation keeps the drive cost aligned with what the installation actually needs — external filtering that already exists, plus environmental hardening and local operator access.
