The 6SL3230-3YE54-0AP0 is a 250 kW SINAMICS G120X general-purpose frequency converter in the largest FSG frame, equipped with a C2 EMC filter. Delivering 644 A at 380–480 V, this is the top-of-range power rating for the G120X series — built for the largest pumps, fans, and compressors in water treatment plants, HVAC systems, and industrial utilities.

C2 EMC — industrial environments without additional filtering

The C2 EMC classification means this drive meets conducted and radiated emission limits for industrial environments per IEC 61800-3 without requiring an external filter. For a 250 kW drive, the integrated C2 filter is a meaningful cost and panel-space saving — an external filter at this power level is a substantial component. In a water treatment plant or pumping station where multiple large drives share a common supply, the C2 compliance ensures the drive does not pollute the mains supply beyond the industrial-environment limits.

250 kW in the FSG platform

At 250 kW and 644 A, the FSG frame represents the upper boundary of the G120X wall-mounted/cabinet-installed format. The drive handles the largest single-motor loads in infrastructure applications: a main cooling-water pump, a district heating circulation pump, or a tunnel ventilation fan. Overload capacity of 150% for 57 seconds provides the headroom to start high-inertia fan rotors and pump impellers without oversizing the drive. The 0AP0 suffix indicates standard coating and no IOP-2 operator panel — the drive is commissioned and monitored via the G120X's standard interface, typically through a remote HMI or the plant's SCADA system over PROFINET or PROFIBUS.
