The Siemens 4EU3022-5AA00-0AA0 is a 3-phase commutating choke (drossel) designed for converter output circuits. The 0.13 mH inductance limits the rate of current rise during commutation, protecting the converter's power semiconductors from di/dt stress.
The 252 A rated value (I_LN) is the continuous current the choke can handle at its 40 °C ambient rating. The 280 A maximum (I_thmax) is the thermal limit under overload — useful for sizing against short-duration peaks in a drive cycle. At DC, the same choke is rated 343.1 A, reflecting the lower RMS heating of DC current vs AC. The 4 % relative inductive voltage drop (u_k) tells you the voltage the choke consumes at rated current; factor this into the drive's available output voltage budget. Thermal class H (180 °C) insulation means the choke can run hot without degrading the winding — important for enclosed panels where airflow is limited. The 210 W coil loss plus 143 W iron core loss (353 W total) must be dissipated; plan for that heat load in your enclosure cooling calculation.
This choke mounts between the converter output and the motor, typically on a sub-panel or chassis baseplate — IP00 means no enclosure protection, so it requires a cabinet. The flat-type terminals accept busbar or cable lugs; plan for 0.211 m depth, 0.3 m width, 0.269 m height when laying out the panel. It is designed for 50 Hz operation; verify compatibility if your drive runs at 60 Hz output.
