Rated for 3-phase AC systems at 780 V operating voltage and 50 Hz, it handles a maximum continuous current of 825 A and a rated current of 743 A — the 825 A figure is the thermal limit under the listed conditions, while 743 A is the continuous duty point for sizing. The inductance is 0.00002 H (20 µH) with a relative inductive voltage drop of 1.2% at rated current, frequency, and voltage — this low drop keeps the voltage sag across the choke minimal, so the drive sees nearly full line voltage under load. ## Deployment context and mounting IP00 means no ingress protection — this choke is intended for installation inside an enclosed panel or cabinet where it is not exposed to dust or moisture. The flat-type connectors suit busbar or cable-lug termination common in high-current converter line-ups. Dimensions are 0.35 m wide, 0.321 m tall, and 0.227 m deep — a substantial footprint that requires panel layout planning for clearance and airflow around the iron core, which dissipates 81.4 W of iron loss plus 321 W of coil loss at rated load. ## Thermal and insulation class Thermal class H per IEC 60085 means the winding insulation can withstand a continuous hot-spot temperature of 180 °C — typical for high-power line reactors where copper losses are significant. The rated ambient temperature is 40 °C, so derating applies if the cabinet ambient exceeds that. At DC rated value the choke carries 1,011 A — useful if the converter operates in a six-pulse or twelve-pulse configuration where the DC link current is higher than the AC line RMS. For a BOM that requires this exact choke, the mature status means it remains specifiable, but lead time and pricing should be confirmed at quote time — not assumed from a catalogue.","metaTitle":"Siemens 4EU3622-0EM00-1BA0 Commutating Choke, 825A, 780V","metaDescription":"Siemens 4EU3622-0EM00-1BA0 commutating choke for converters, 3-phase, 825A max, 743A rated, 780V AC, 50Hz, IP00, flat connectors.
