It carries a maximum current of 275 A and a rated current of 247.5 A at 460 V AC, 60 Hz. The 0.11 mH inductance limits di/dt and reduces harmonic stress on the converter's semiconductors — a critical parameter when the drive is feeding a motor load with fast-switching IGBTs. The relative inductive voltage drop is 3.98 % at the rated operating point. That figure determines the voltage headroom the converter must supply to compensate for the choke's impedance — factor it into the DC-link voltage budget during drive sizing. ## Thermal and mechanical constraints Rated for a 40 °C ambient with thermal class H insulation per IEC 60085, which means the winding insulation withstands a 180 °C hot-spot temperature. The total power loss splits into 160 W in the coil and 127 W in the iron core at rated load — that 287 W must be dissipated into the surrounding air. IP00 means no enclosure protection; the choke requires a cabinet with forced ventilation or sufficient free-air volume to keep the core temperature within limits. Dimensions are 0.27 m wide, 0.248 m tall, and 0.187 m deep. The main circuit connects via flat-type terminals — verify bus-bar or cable-lug compatibility with your existing panel layout before ordering.","metaTitle":"Siemens 4EU2722-0ER00-1BA0 Commutating Choke, 275A, 460V AC","metaDescription":"Siemens 4EU2722-0ER00-1BA0 commutating choke for converter drives. 3-phase, 275A max, 460V AC, 0.11 mH, IP00, thermal class H.
