Its 0.081 mH inductance at 405 A rated current (450 A maximum) gives a relative inductive voltage drop of 4 % at rated frequency — a standard value that keeps the DC-link voltage drop predictable while still smoothing the commutation notches. Rated for 500 V AC, 50/60 Hz, and a 40 °C ambient, this open-frame (IP00) choke is intended for panel mounting where the enclosure provides the physical protection. The flat-type terminals accept busbar or cable lugs for the main current circuit — no DIN-rail clip here; it bolts directly into the cabinet floor or backplate. Thermal class H (180 °C) insulation means the coil can run hot without degrading the magnet wire varnish — important when the choke is stacked near other heat sources in a dense drive panel. Total copper and iron losses sum to 520 W (300 W coil + 220 W core), so plan for ventilation or forced airflow around the mounting footprint. The choke measures 0.35 m wide by 0.321 m tall by 0.227 m deep — a substantial block that needs a clear panel area free of adjacent heat-sensitive components. The flat-type terminals are sized for bolted connections; verify that your busbar or lug pattern matches the terminal spacing (not listed here, so confirm against the nameplate or dimensional drawing before panel layout).","metaTitle":"Siemens 4EU3622-7AA00-0AA0 Commutating Choke, 405A, 0.081mH","metaDescription":"Siemens 4EU3622-7AA00-0AA0 commutating choke for converters, 3-phase, 500V AC, 405A rated, 0.081mH, IP00, thermal class H.
