The Siemens 4EU3622-8DA00-1BA0 is a 3-phase commutating choke (line reactor) designed for converter applications. It carries a rated current of 360A at 750V AC, with a peak current capability of 500A and a DC-rated value of 490.1A — the DC figure matters if you're using it on the DC link side of a drive, not just the AC input. Inductance is 0.11 mH (110 µH) with a 4% relative inductive voltage drop at rated conditions. That 4% figure tells you the voltage drop across the choke at full load — critical for sizing the DC bus voltage margin in a drive system. The choke is IP00 — open-frame, no enclosure — so it's intended for mounting inside a cabinet where the panel provides the environmental protection. Thermal class H (180°C rated insulation) means it can handle sustained high-temperature operation in a crowded enclosure.
Sizing and fit
Dimensions: 0.35 m wide × 0.321 m tall × 0.227 m deep. Termination is via flat-type connectors (busbar-style), not ring lugs or screw clamps. The panel wiring design needs to account for that interface — typically a bolted busbar connection rather than a cabled termination. Coil power loss 320 W, iron core power loss 180 W.
