The Siemens 4EU3622-7CA00-0AA0 is a 3-phase commutating choke for converter applications, rated for AC 500 V and 560 A maximum AC current, with a rated operational current of 504 A at 50 Hz. The 0.049 mH inductance limits current rise during commutation, protecting the converter's semiconductors from di/dt stress. Thermal class H insulation (180 °C) handles the 293 W coil loss plus 160 W iron-core loss at 40 °C ambient without derating the thermal margin.
Integration dimensions
At 0.35 m wide, 0.321 m tall, and 0.227 m deep, this choke occupies a substantial footprint — roughly the size of a small suitcase. The flat-type main-circuit connectors expect busbar or heavy cable lugs; plan for adequate bending radius and clearance to adjacent components. The 700 A peak current rating and 686.2 A DC rated current confirm it is sized for high-power converter output stages, typically feeding a motor drive or a DC-link bus.
