What this choke does in the drive line
The Siemens 4EU3022-0LA00-1BA0 is a 3-phase commutating choke (Kommut.-Drossel f. Stromrichter) for converter applications, rated for 433 V AC at 50 Hz. It handles a maximum current of 820 A and a continuous rated current of 738 A, with a DC rated value of 1004.9 A — meaning it's sized for the output side of a large converter to limit commutation notches and reduce harmonic stress on the DC link and semiconductor switches. The 0.015 mH inductance and 2% relative inductive voltage drop at rated conditions are what govern its filtering effect; the 233 W coil loss and 75.3 W iron-core loss tell you the thermal load to plan for in the enclosure.
The choke measures 0.3 m wide by 0.269 m tall by 0.211 m deep — a substantial block that needs floor or back-panel mounting, not a DIN rail clip. IP00 protection means it's open-frame; install it inside a cabinet that provides the environmental seal.
