It's a 3-phase, 660V AC rated choke with a rated current of 315A and a maximum current of 350A, with an inductance of 0.03 mH. The 315A rated current (350A max) is the continuous thermal limit at 40°C ambient — derate above that. The 660V AC operating voltage covers 400V and 480V line supplies with headroom. The 60Hz operating frequency matches standard industrial line frequencies; it'll run at 50Hz without issue but the inductive reactance drops proportionally. The 242W coil loss plus 80W iron loss (322W total) is the heat you need to vent — IP00 means no enclosure, so it's intended for cabinet mounting where forced air or natural convection handles the thermal load. Class H insulation (180°C thermal class) gives margin for hot spots in the winding. The 0.3m width, 0.269m height, and 0.221m depth footprint means it takes up a fair chunk of backplate real estate — plan for a dedicated mounting zone, not a DIN-rail clip. The flat-type terminals for the main circuit accept busbar or cable lugs; you'll need a torque wrench for the connection. IP00 means no touch protection — locate it behind a locked cabinet door or with a physical guard if maintenance personnel work near live parts.","metaTitle":"Siemens 4EU3022-0AK00-4BA0 Commutating Choke, 315A, 660V, 3-","metaDescription":"Siemens 4EU3022-0AK00-4BA0 commutating choke for converter, 315A rated, 660V AC, 3-phase, 0.03 mH, IP00, class H.
