It carries a rated continuous current of 1008 A and a maximum current of 1120 A at 60 Hz, with a rated inductance of 25 µH and a relative inductive voltage drop of 4% at rated conditions. The 4% impedance is a typical value for drive input chokes, providing enough harmonic attenuation to protect the converter DC bus without excessive voltage drop under load. Rated for a 40 °C ambient with Class H insulation (180 °C thermal class per IEC 60085), this choke dissipates 459 W in the coil and 364 W in the iron core at full load — total 823 W of heat that must be removed from the enclosure. ## Integration into a drive line-up The choke measures 0.46 m wide × 0.435 m high × 0.265 m deep — a substantial footprint that requires floor-mounting or a heavy-duty shelf inside the cabinet. Main circuit connections are via flat-type terminals, which typically accept busbar or large cable lugs. The 1120 A maximum rating means this choke pairs with drives in the 500–600 hp range at 460 V; verify that the drive manufacturer's recommended line reactor impedance matches the 4% value.","metaTitle":"Siemens 4EU4351-0UC00-0A Mains Choke, 1120 A, 460 V, 60 Hz","metaDescription":"Siemens 4EU4351-0UC00-0A mains choke for frequency converters.
