What this mains choke does for the drive line
The Siemens 4EU3622-0EC00-1BA0 is a three-phase mains choke (line reactor) for the input side of a variable-frequency drive. Rated 784 A continuous with a 871 A maximum at 47 Hz.
Rated current 784 A at 480 V AC, 3-phase, 47 Hz — thermal continuous rating at 50 °C ambient. The 871 A maximum figure reflects the short-time overload capability. Power loss splits into coil loss 268.9 W and iron-core loss 189.4 W — total roughly 458 W dissipated as heat. That heat stays inside the enclosure; IP00 means no housing, so the choke must be mounted in a clean, dry, ventilated cabinet (or a dedicated electrical room). Class H insulation (180 °C thermal class per IEC 60085) gives a generous temperature margin for high-ambient or overload conditions.
The choke measures 0.35 m wide × 0.321 m tall × 0.237 m deep — a substantial block, not a DIN-rail component. Main circuit connections are flat-type terminals (bus-bar or cable-lug interface), typical for high-current line reactors. Plan for rigid bus work or large-gauge cable lugs; the terminals expect a bolted connection, not a spring clamp.
The lifecycle stage is recorded as mature — meaning it's an established, stable design with no active phase-out notice. It carries UL/CSA recognition per EN 61558, so it's accepted for North American panels that require listed components. The IP00 protection class means no ingress protection; install in a cabinet that keeps out dust and moisture.
