The Siemens 4EU2422-0BA00-0AA0 is a 3-phase commutating choke (line reactor) for converter applications, rated at 81.9 A continuous with a maximum of 91 A and a peak current of 114 A. It operates at 500 V AC, 50 Hz, with a rated inductance of 0.33 mH and a relative inductive voltage drop of 4%.
The 81.9 A rated current (I LN) is the continuous thermal current at 40 °C ambient — size your drive's input for this, not the 91 A maximum. The 114 A peak handles short-duration inrush or transient loads without saturating the core. The 4% voltage drop at rated current is typical for a commutating choke; it limits di/dt during converter switching and reduces harmonic distortion on the line side. The 0.33 mH inductance value is what governs the dV/dt smoothing — match it to your drive's DC-link design. Class H insulation and 122 W coil loss plus 32 W iron loss mean this choke runs hot. The IP00 open-frame construction requires mounting inside a ventilated enclosure.
This is a panel-mount component, not DIN-rail. Dimensions are 0.225 m wide, 0.21 m high, 0.136 m deep. Terminals are flat-type connectors for the main current circuit — expect ring lugs or bus-bar connections, not spring-cage. Designed for converter input or output duty per EN 61558-2-20. The 3-phase, 500 V AC, 50 Hz rating matches standard European industrial supply. Verify your drive's nominal voltage and frequency match before specifying.
