It limits current rise and reduces harmonic distortion on the line side of a converter, protecting both the drive and the upstream supply. Rated for 400 V AC at 50 Hz, it carries a maximum continuous current of 250 A and a rated current of 225 A, with an inductance of 0.112 mH (110 µH). The 4% relative inductive voltage drop (on the measurement level) means this choke introduces a predictable impedance that helps the converter meet line-side harmonic limits without excessive voltage sag under load. At 225 A continuous, the total power loss splits between the coil (167 W) and the iron core (90 W), so panel ventilation must account for roughly 257 W of heat rejection at full rated current. With an IP00 protection class, this choke has no enclosure — it is an open-frame component intended for installation inside a switchgear cabinet or drive panel. The flat-type main circuit terminals accept busbar or cable lugs; plan for adequate clearance to live parts per local wiring regulations. ## Thermal class and ambient rating Rated for a 40 °C ambient temperature and wound to thermal class H per IEC 60085, meaning the insulation system withstands a continuous hot-spot temperature of 180 °C. This gives headroom for installations where the choke shares a cabinet with heat-producing drives, as long as the ambient air at the choke intake stays at or below 40 °C. ## Physical dimensions The choke measures 0.270 m wide, 0.248 m high, and 0.187 m deep. These dimensions are for the body only — allow additional space for cable bending radius and busbar connections above the flat terminals.","metaTitle":"Siemens 4EU2722-3AA00-0AA0 Commutating Choke, 250A, 225A Rat","metaDescription":"Siemens 4EU2722-3AA00-0AA0 commutating choke for 3-phase converters. 250A max, 225A rated, 0.112mH, 400V AC, 50Hz, IP00.
