It handles a maximum AC current of 246 A and a rated operational current of 221.4 A, with an inductance of 0.12 mH. The relative inductive voltage drop is 4% at rated current, voltage, and frequency. The 0.12 mH inductance and 4% voltage drop define the commutation notch filtering — this choke is sized to limit di/dt and suppress harmonics for a specific converter DC-link current. The 301.4 A DC rated value tells you the choke can also sit in the DC link path, not just the AC input. ## Deployment Context IP00 means no ingress protection — this choke is for installation inside a cabinet or enclosure, not in a washdown or outdoor location. The flat-type terminals accept busbar or crimp lugs, not standard wire ferrules. Thermal class H per IEC 60085 means the insulation system can sustain 180 °C hot-spot temperature, which is typical for high-power converter chokes running at 160 W coil loss plus 127 W iron-core loss at 50 °C ambient. Mount it with clearance for airflow; forced ventilation is advisable above 246 A continuous.","metaTitle":"Siemens 4EU2722-0FA00-1BA0 Commutating Choke, 246A, 400V AC","metaDescription":"Siemens 4EU2722-0FA00-1BA0 commutating choke for converter. 3-phase, 400V AC, 246A max, 0.12 mH, IP00, thermal class H.
