Stromrichter) designed for line-side or DC-link use in converter and drive systems. It carries a continuous rated current of 1800 A at 750 V AC, 50 Hz, with an inductance of 24 µH and a relative inductive voltage drop of 4 % at rated conditions. The IP00 open-frame construction means it mounts inside a cabinet or enclosure — no touch protection on the choke itself, so the panel must provide the guarding. The 1800 A rating (both maximum and rated value) sets the thermal current-carrying capability at 40 °C ambient. That figure governs the busbar or cable sizing upstream and downstream — the choke itself won't be the bottleneck at that current level. The 750 V AC operating voltage matches common 690 V line-to-line systems with headroom; verify the converter's DC-link voltage does not exceed this rating. Total power loss sums to 1460 W (1000 W in the coil, 460 W in the iron core). That heat must be removed from the enclosure — forced ventilation or a derated fill factor in a sealed cabinet. The thermal class H insulation (IEC 60085) allows a 180 °C hot-spot temperature, so the choke can run hot, but the surrounding components may not. The flat-type terminals (flat connector) are sized for bolted busbar connections — not wire lugs or spring cages. Plan for a busbar interface rather than cable tails. ## Integration notes Physical footprint: 0.518 m wide × 0.318 m deep × 0.565 m tall. That is a substantial component — roughly half a meter each way — so verify the enclosure depth and backplate space before committing. The IP00 rating means no integrated enclosure; mount it on a non-flammable, grounded panel with clearance to adjacent live parts per IEC 61439-1.","metaTitle":"4EU5021-0AB10 Siemens Commutating Choke, 1800 A, 750 V AC, 5","metaDescription":"Siemens 4EU5021-0AB10 commutating choke for converter, 3-phase, 1800 A rated, 750 V AC, 50 Hz, 24 µH, IP00, flat-type terminals.
