The Siemens 4EU3022-0EP00-1BA0 is a three-phase mains choke (line reactor) designed for installation ahead of a frequency converter (Netzdrossel f. FU). It smooths line-side harmonics and limits inrush current, protecting the drive's rectifier stage. Rated for 488 A continuous (542 A maximum) at 690 V AC, 60 Hz, with an inductance of 27 µH and a relative inductive voltage drop of 1.28 % at rated current.
Rated 488 A at 40 °C ambient, Class H insulation. 1.28 % voltage drop at rated current. 690 V rating matches line-to-line supply.
Deployment context
IP00 open-frame. Flat-type terminals. Dimensions: 0.221 m depth, 0.3 m width, 0.269 m height.
