It operates at 750 V AC, 50 Hz, and carries an inductance of 0.000055 H. ## Sizing and thermal reality Total power loss at rated load is 480 W coil plus 285 W iron core. At IP00, heat dissipates into cabinet air — plan forced ventilation if ambient exceeds 40 °C. This part carries a mature lifecycle status. ## Physical fit and connections Dimensions: 0.46 m wide × 0.435 m high × 0.265 m deep. Main circuit connections are flat-type terminals. IP00 rating means no integral enclosure.","metaTitle":"Siemens 4EU4321-6DA00-0A Commutating Choke, 720A, 750V","metaDescription":"Siemens 4EU4321-6DA00-0A commutating choke for converters. 3-phase, 720A rated, 750V AC, 50Hz, IP00, flat connectors.
