The 6SL3230-3YE50-1AF0 is the F-suffix 160 kW G120X with C2 EMC and 3C3 conformal coating in FSG frame. Delivering 408 A at 380–480 V, it is specified for medium-to-large pump and fan drives in corrosive industrial atmospheres — wastewater treatment, coastal pumping, chemical-process utilities — where tighter C2 emission limits apply on shared supply transformers.

C2 + 3C3 at 160 kW — tighter EMC, tough environment

The C2 EMC filter meets the stricter conducted-emission limits for installations where the drive's supply transformer also feeds auxiliary building loads — instrumentation, lighting, HVAC — alongside the pump drives. The 3C3 conformal coating protects the drive's PCBs against trace corrosive gases (hydrogen sulphide, sulphur dioxide) that are present at parts-per-million levels in wastewater and coastal atmospheres. At 160 kW, the drive is a 15–20-year capital asset; the coating is an insurance policy against gradual corrosion of unprotected copper traces and component leads over that service life.

No IOP-2 — remote operation as standard

The 1AF0 omits the IOP-2 operator panel. At 160 kW, the drive is commissioned from the engineering framework over PROFINET and monitored from the plant's SCADA or DCS. The F-suffix panel code designates one of two equivalent no-panel ordering variants (F and P) — functionally identical, differing only in the catalog variant identifier within Siemens' product system.
