It limits current rise during commutation, reduces harmonic distortion, and protects the converter's semiconductor devices from di/dt stress. The part is rated for a maximum continuous current of 315 A, with a rated operating current of 283.5 A at 40 °C ambient, and a peak current capability of 394 A. The rated voltage is 750 V AC, and the inductance is 0.14 mH (140 µH) per phase. The relative inductive voltage drop is 4% at the rated current, frequency, and voltage — a standard figure for line reactors sized to limit inrush without excessive voltage sag under load. Power loss splits into 308 W in the coil and 123 W in the iron core at rated conditions, giving a total of 431 W to dissipate in the enclosure. The 315 A maximum rating and 283.5 A continuous rating define the thermal envelope. For a 400 V or 480 V drive system, this choke is sized for a converter with a nominal input current in the 280–315 A range. The 394 A peak rating covers short-duration overloads typical during motor acceleration. The 0.14 mH inductance per phase provides enough impedance to limit commutation notches but keeps the voltage drop under 5% at full load — important for maintaining DC bus voltage on the drive. The operating frequency range is 0 to 50 Hz, so this choke is intended for line-frequency (50 Hz mains) applications, not for use on the output side of a PWM drive. Thermal class H per IEC 60085 means the insulation system can withstand a 180 °C hot-spot temperature, which gives good margin above the 40 °C ambient rating. The flat-type terminals accept busbar or cable lug connections typical for this current class. ## Physical integration The choke measures 0.35 m wide, 0.321 m tall, and 0.227 m deep. These dimensions are for the body only — allow additional clearance for the flat-type terminal connections and for airflow around the coil and core. The 431 W total power loss requires forced ventilation or a suitably sized cabinet to keep the internal temperature rise within limits.","metaTitle":"Siemens 4EU3622-6DA00-0AA0 Commutating Choke, 315A, 750V","metaDescription":"Siemens 4EU3622-6DA00-0AA0 3-phase commutating choke for converters.
