It limits current rise and reduces harmonic distortion on the AC line feeding a variable-frequency drive or DC drive. Rated for 400 V AC at 50 Hz, it carries a maximum continuous current of 355 A and a rated current of 319.5 A — the 319.5 A figure is the thermal design point for continuous duty at 40 °C ambient. That 4 % drop is the key selection parameter: it tells you the choke will limit inrush and smooth commutation without dropping excessive voltage across the reactor under load. This is an IP00 open-frame choke — no enclosure, no finger-safe cover. It mounts inside a panel or drive cabinet where the ambient stays at or below 40 °C. Dimensions are 0.3 m wide by 0.269 m tall by 0.211 m deep — factor that into your gland-plate layout and sidewall clearance for the flat connectors. Thermal class H insulation (180 °C continuous) means the winding can run hot without degrading the magnet wire. The coil dissipates 220 W and the iron core another 143 W — total 363 W of heat that must be vented from the enclosure. If you're packing this into a sealed cabinet, add forced ventilation or oversize the cabinet to keep the internal rise under the 40 °C ambient rating.","metaTitle":"Siemens 4EU3022-1AA00-0AA0 Commutating Choke, 355A, 400V, 50","metaDescription":"Siemens 4EU3022-1AA00-0AA0 commutating choke for converter. 3-phase, 400V AC, 50Hz, 355A max, 319.5A rated, 0.077mH, IP00.
