The Siemens 4EU3022-5CA00-0AA0 is a 3-phase commutating choke (line reactor) for converter applications, rated for a maximum continuous current of 200 A and a nominal current of 180 A at 50/60 Hz. It's built for a 750 V AC operating voltage with an inductance of 0.28 mH and a relative inductive voltage drop of 4% at rated conditions — that 4% drop is the key number for sizing the DC bus or AC line impedance on a drive input. The IP00 enclosure means it's an open-frame component — no splash or dust protection — so it mounts inside a cabinet, not out on the floor where coolant or washdown hits it.
The thermal class is H per IEC 60085, which means the insulation system can handle a 180 °C hot-spot temperature — important if you're pushing the full 220 W coil loss plus 160 W iron loss in a warm cabinet.
Connections are flat-type terminals for the main current circuit — no screw-clamp or ring-lug here. Plan for busbar or flat-cable termination when laying out the panel. Dimensions are 0.3 m wide by 0.269 m tall by 0.211 m deep — it takes up a fair chunk of panel real estate, so check your enclosure depth and side clearance before committing the backplate layout.
