The Siemens 4EU3022-2BA00-0AA0 is a 3-phase commutating choke for converter applications, rated at 400V AC and 50 Hz. It handles a continuous AC current of 360A (400A max AC) and a DC rated current of 490.1A, with a peak rating of 500A. The 56 µH inductance limits the rate of current rise during converter commutation, reducing stress on the semiconductors and smoothing the DC link.
The 360A AC rated current (I_LN) is the continuous load it can carry in a 50 Hz converter circuit at 40°C ambient — size your upstream breaker and cabling for at least this. The 4% relative inductive voltage drop (UK) means the choke will drop 16V at rated current on a 400V line; factor that into your DC bus voltage budget. Class H insulation (thermal class per IEC 60085) means the winding can sustain 180°C hot-spot temperature — this choke is built for the thermal cycling inside a converter cabinet, not a clean 40°C panel. The 220W coil loss plus 102W iron core loss (322W total at rated load) must be ventilated out; IP00 means no enclosure protection, so mount it in a cabinet with forced airflow or sufficient natural convection.
This choke sits between the converter's input rectifier and the DC-link capacitors (or on the AC line side for line-commutated drives). The flat-type terminals accept busbar or heavy cable lugs — plan for M8 or M10 ring terminals, not spring-cage wire. Dimensions are 0.3m wide by 0.269m tall by 0.211m deep, so it needs a dedicated mounting plate or chassis rail inside the enclosure.
