FU), 3-phase, 500V AC, 90A rated current, 0.37mH inductance, IP00, flat-type terminals.","salesMarkdown":"## Mains Choke for Variable Frequency Drives The Siemens 4EU2552-3UB00-0AA0 is a three-phase mains choke (line reactor) designed for use with variable frequency drives. It carries a rated current of 90 A and a maximum current of 100 A, with an inductance of 0.37 mH and a 4% relative inductive voltage drop at rated conditions. This choke sits between the supply and the drive input to reduce harmonic distortion, limit inrush current, and protect the drive's DC bus from line transients. The 0.37 mH inductance and 4% impedance at rated current are matched to a typical drive input stage — this isn't a random value; it's sized to keep harmonic currents below IEEE 519 thresholds for most 90–100 A drive installations. The 139 W coil loss and 44 W core loss total 183 W heat dissipation at full load — factor that into enclosure ventilation. Thermal class H insulation, 40 °C ambient rating. IP00 enclosure, open-frame. Flat-type terminals for main circuit. Designed to EN 61558-2-20 and carries UL/CSA recognition per the manufacturer's marking. The UL/CSA mark means it's accepted in North American panels without a separate component evaluation — a practical gate for export builds or multi-site BOMs.","metaTitle":"Siemens 4EU2552-3UB00-0AA0 Mains Choke, 90A, 0.37mH, 3-Phase","metaDescription":"Siemens 4EU2552-3UB00-0AA0 mains choke for variable frequency drives. 90A rated, 0.37mH, 3-phase, 500V AC, 50Hz.
