Stromrichter) designed for line-commutated converters. It sits between the AC supply and the converter input to limit the rate of rise of fault current and reduce harmonic distortion on the line side. Rated for 294.3 A continuous with a maximum short-time rating of 327 A at 60 Hz, this choke handles the current ripple and commutation notches a 6-pulse or 12-pulse drive throws back at the mains. The 294.3 A rated current is the continuous thermal current at the 50 °C ambient temperature rating. The 327 A maximum is the overload capability at 60 Hz — this is not a continuous rating; it's the peak the choke can sustain briefly during a converter fault or inrush event. The 0.09 mH inductance with a 4% relative inductive voltage drop means the choke presents about 4% of the line voltage as inductive drop at rated current — a standard value for commutating chokes that keeps the DC-link voltage drop within acceptable limits for most drives. The 400 V AC operating voltage matches standard 400 V three-phase industrial mains. Thermal class H means the insulation system is rated for 180 °C hot-spot temperature — this choke can live inside a warm cabinet without derating, as long as the ambient stays at or below 50 °C. This is a panel-mount component — IP00 means no enclosure protection, so it must be installed inside a cabinet with at least IP2X protection. The flat-type terminals accept busbar or cable lug connections typical of larger power components. Dimensions are 0.3 m wide × 0.269 m high × 0.211 m deep — plan for a footprint roughly 300 × 270 mm on the mounting plate, plus clearance for airflow. The 205 W coil loss plus 160 W iron core loss totals 365 W of heat to vent out of the enclosure; factor that into the cabinet cooling calculation.","metaTitle":"Siemens 4EU3022-0EH00-1BA0 Commutating Choke, 327A, 3-Phase","metaDescription":"Siemens 4EU3022-0EH00-1BA0 3-phase commutating choke for converters.
