The 0.098 mH inductance and 4% relative inductive voltage drop are sized to limit current rise and reduce harmonics on the converter's input or DC link — common in variable-frequency drive and rectifier front ends. The 270 A rated current (I LN) and 300 A maximum (Ithmax) tell you this choke is sized for a 270 A continuous load with headroom to 300 A — typical for a 200–250 hp drive at 480 V. The 4% voltage drop at rated current is the standard impedance for most drive line reactors; it limits fault current and smooths the DC bus without excessive voltage sag. The 0.098 mH inductance is fixed — no taps — so verify your drive's minimum line impedance requirement before specifying. IP00 means no enclosure — this is an open-frame component intended for a ventilated cabinet or panel. The flat-type terminals accept bus bar or large cable lugs, not spring-cage or screw-clamp connectors. Thermal class H insulation means the winding can handle a 180 °C hot-spot temperature, so it survives the heat inside a crowded converter cabinet. Mounts in a drive panel or converter cabinet — the 0.3 m width, 0.269 m height, and 0.221 m depth (–) need a clear footprint and ventilation around the IP00 core. Common on the input side of a 480 V three-phase drive to reduce harmonic distortion and protect the rectifier from line spikes, or on the DC link for current smoothing.","metaTitle":"Siemens 4EU3022-0EK00-0BA0 Commutating Choke, 270A, 480V, 3-","metaDescription":"Siemens 4EU3022-0EK00-0BA0 commutating choke for converters.
