What it is and where it fits
The Siemens 4EU3022-7AA00-0AA0 is a three-phase commutating choke for converter input circuits. It limits current rise and harmonics on the AC line. Rated 180 A continuous with a 200 A maximum, it handles 690 V AC at 50 Hz and delivers 0.00024 H inductance with a 4% voltage drop. This is an open-frame (IP00) component — no enclosure, so it mounts inside a cabinet or panel where the environment is clean and dry. The flat-type terminals accept busbar or cable lugs for the main circuit connection. Thermal class H per IEC 60085 means the winding insulation withstands 180 °C hot-spot temperature, which suits the high ambient (40 °C rated) and the combined copper and iron losses of 342 W total.
Key ratings and what they mean for your drive line
The 180 A rated current (200 A max) is the continuous thermal current (Ith) at 40 °C ambient — this is the current the choke can carry indefinitely without exceeding the Class H temperature rise. For a 690 V drive system, that translates to roughly a 200–250 kW motor load depending on the drive topology and overload profile. The 0.00024 H inductance with a 4% voltage drop at 50 Hz limits di/dt and reduces harmonic distortion. A 4% impedance is a common choice for general-purpose drive applications. The 342 W total power loss (210 W copper + 132 W iron) is heat that must be managed inside the enclosure. At 180 A, that's about 1.9 W per amp — factor this into your panel ventilation or forced-air cooling calculation.
Lifecycle and sourcing reality
The design complies with EN 61558-2-20, the standard for chokes and reactors for power supplies and converters. This is the relevant IEC safety standard for this component class.
