What this choke does in a drive cabinet
The Siemens 4EU2722-0FG00-0BA0 is a 3-phase mains choke (Netzdrossel f. FU) sized for frequency converter input lines. Its 200 A maximum AC current and 180 A rated operational current at 500 V AC, 60 Hz, with 75 µH inductance and a 2% relative inductive voltage drop, mean it smooths line-side harmonics and limits inrush current for drives in that current class. The IP00 enclosure (no protection against dust or moisture) tells you this mounts inside a panel or cabinet — not on the machine frame where washdown or dust exposure is a risk. Thermal class H insulation (IEC 60085) handles the 143 W coil losses plus 46 W iron core losses at 40 °C ambient, so it runs hot but stays within rating in a ventilated enclosure.
Physical fit and connection
Dimensions: 0.208 m depth, 0.27 m width, 0.248 m height. The main current circuit terminates on flat-type connectors — expect busbar or compression-lug terminations, not screw-clamp or spring-cage. Panel builders should verify the flat-connector pitch and hole pattern against their existing busbar layout before committing the footprint.
