The Siemens 4EU2722-5BA00-0AA0 is a 3-phase commutating choke for converter drives, rated 400V AC at 50Hz. It handles a maximum AC current of 224A and a peak current of 280A.
The 224A AC maximum current and 201.6A AC rated current set the continuous operating envelope — size your upstream protection and cabling for at least this. The 274.5A DC rated value covers the DC-link side if you're using it in a six-pulse rectifier configuration. Thermal class H insulation per IEC 60085 means the winding can sustain 180°C hot-spot temperature — common for converter-duty chokes that see harmonic-rich current waveforms. The 174W coil loss plus 75W iron core loss total about 249W of heat to vent; in a sealed enclosure that's non-trivial. IP00 means no ingress protection — this choke needs to live inside a cabinet, not on the plant floor.
Mounting dimensions: 0.27m wide, 0.248m tall, 0.187m deep. That's about 10.6" x 9.8" x 7.4" — a substantial block. The flat-type terminals accept busbar or crimp lugs, not spring-cage or screw-clamp wire ends. Plan for rigid bus connections; the 224A continuous current needs a cross-section that flat terminals can deliver without overheating the termination point.
