It smooths current commutation and limits di/dt and peak fault currents on the AC side of a 3-phase converter bridge. Rated for 450 A continuous at 500 V AC, 50 Hz, with a maximum current of 500 A and a DC-side rating of 612.7 A, it handles the full converter throughput in a medium-power drive or rectifier line-up. Inductance is 0.000073 H (73 µH), and total power loss splits into 280 W in the coil and 200 W in the iron core at rated conditions — 480 W total heat to manage inside the enclosure. ## Deployment context and mounting This is an open-frame component with IP00 protection — no enclosure, no ingress sealing. The main circuit connects via flat-type terminals (busbar or cable lug), so plan for bolted connections, not spring clamps. Physical footprint: 0.35 m wide, 0.321 m tall, 0.227 m deep — roughly 14 by 13 by 9 inches. That is a substantial block; verify the gland plate and backpanel clearance before committing the layout. ## Thermal class and lifecycle Thermal class H per IEC 60085 means the insulation system withstands a continuous hot-spot temperature of 180 °C. That gives headroom for the 480 W total loss in a warm cabinet, but the rated ambient is 40 °C — derate if your enclosure ambient runs higher. Lifecycle status is listed as mature. That typically means the design is stable and not subject to short-term obsolescence, but it is not a current-promotion item. Availability is confirmed at time of RFQ through independent distribution channels.","metaTitle":"Siemens 4EU3622-8AA00-0AA0 Commutating Choke, 450A, 500V, 3-","metaDescription":"Siemens 4EU3622-8AA00-0AA0 commutating choke for converter, 3-phase, 450A rated, 500V AC, 50Hz, IP00, thermal class H.
