The 6SL3230-3YE50-1CF0 is a 160 kW SINAMICS G120X in FSG frame, fitted with a C3 EMC filter and 3C3 conformal coating. Delivering 408 A at 380–480 V, it sits between the 132 kW and 200 kW steps in the G120X power range — a power level commonly specified for medium-to-large pump and fan loads in water treatment plants, district heating systems, and industrial cooling circuits.

160 kW — the mid-to-large infrastructure step

At 160 kW and 408 A, this drive handles pump and fan motors that are large enough to be the primary loads in a municipal facility but not so large that they demand the 250 kW flagship. Typical applications include a secondary cooling-water pump, a booster pump in a water distribution network, or a forced-draft fan in an industrial boiler system. The G120X's overload rating at this power level is 110% for 60 seconds — sufficient for the relatively steady-state duty of centrifugal pumps and fans, where start-up current peaks briefly before settling to the operating point.

C3 + 3C3 — industrial EMC with environmental protection

The C3 EMC filter is the standard classification for drives on dedicated industrial transformers — the typical topology in pumping stations and utility buildings. The 3C3 conformal coating adds protection against hydrogen sulphide and other corrosive trace gases, making this variant appropriate for wastewater treatment plants, coastal installations, and chemical-process environments where the atmosphere is not overtly corrosive at the time of installation but is chemically active over the 15–20 year service life of the drive.
