The 0.4 mH inductance with a 4% relative inductive voltage drop means it limits di/dt and smooths commutation notches — critical for protecting converter IGBTs from reflected wave and switching transients on longer motor cables. IP00 means it is an open-frame component — no finger-safe enclosure. It mounts inside a cabinet, not on the panel surface. Flat-type terminals take busbar or cable lugs; plan for a dedicated gland plate or busbar drop. Dimensions are 0.225 m wide × 0.21 m tall × 0.136 m deep. Coil losses run 120 W; iron-core losses add 41 W. The 91 A maximum and 81.9 A rated at 500 V AC are the headline numbers. The 81.9 A is the continuous current under rated conditions; the 91 A is the thermal limit — do not size a drive expecting to pull 91 A continuously through this choke without checking the thermal derating curve above 40 °C. At DC, the rated current is 111.5 A — higher than the AC rating because the core does not see the same AC flux swing. If you are using this in a DC-link application (e.g., between a rectifier and inverter), the DC current capability is the relevant figure. The 4% relative inductive drop at rated current and frequency means the choke drops about 4% of the line voltage across its impedance. That is typical for a commutating choke — enough to limit fault current rise rate without dropping excessive voltage under load.","metaTitle":"Siemens 4EU2422-3AA00-0AA0 Commutating Choke, 91A, 500V, 3-P","metaDescription":"Siemens 4EU2422-3AA00-0AA0 commutating choke for converters.
