The rated inductance is 0.12 mH, with a relative inductive voltage drop of 4% at rated current and frequency. The 355 A maximum at 50 Hz (319.5 A rated continuous, 444 A peak) tells you this choke is sized for a converter feeding a motor or load drawing around 320 A RMS in steady state — think large pumps, compressors, or conveyor drives on 400–690 V class systems. The 0.12 mH inductance and 4% voltage drop are matched to the converter's commutation needs; swapping in a choke with significantly different inductance changes the DC-link ripple and can stress the IGBTs. IP00 means it's open-frame — no enclosure, so it mounts inside a cabinet. The flat-type terminal connections accept busbar or cable lugs. Dimensions are 0.35 m wide × 0.321 m tall × 0.227 m deep. ## Thermal and environmental limits Rated for 40 °C ambient with thermal class H insulation — that's a 180 °C temperature class per IEC 60085, meaning the winding can handle sustained hot-spot temperatures up to 180 °C.","metaTitle":"Siemens 4EU3622-7DA00-0AA0 Commutating Choke, 355A, 750V, 0.","metaDescription":"Siemens 4EU3622-7DA00-0AA0 commutating choke for converters, 3-phase, 750V AC, 355A max, 0.12mH, IP00, thermal class H.
