The Siemens 4EU3022-0AA00-0AA0 is a 3-phase commutating choke (also called a line reactor or converter choke) designed for use with power converters and drives. It sits between the converter and the AC line, limiting current rise rates and reducing harmonic distortion. Rated for 315 A AC maximum at 400 V and 50 Hz, it handles the inrush and switching transients typical of motor-drive applications.
The 315 A AC maximum and 283.5 A AC operational current define the continuous motor-load current this choke can support. The 386 A DC rated current covers DC-link applications.
Physical Integration
Dimensions: 0.3 m wide, 0.269 m high, 0.211 m deep. The flat-type connector requires busbar or cable lugs — no screw-clamp terminals. Mounting is via the chassis; no DIN-rail clip is provided. Plan for a panel cutout or mounting plate that accommodates the footprint and allows airflow around the open-frame windings.
