FU). It smooths current harmonics and limits inrush, protecting both the drive and the upstream supply. Rated for 690 V AC at 50 Hz, it carries a maximum continuous current of 63 A and a rated operating current of 56.7 A. The 0.4 mH inductance with a 2 % relative voltage drop at rated conditions means it's sized for moderate harmonic mitigation without excessive voltage sag under load. With an IP00 protection class, this choke is an open-frame component intended for installation inside a control cabinet or enclosure — not for standalone outdoor or washdown duty. The flat-type terminals accept busbar or cable lugs, common in panel builds where high-current three-phase runs are landed on a bus. The 56.7 A rated operating current (I LN) is the current at which the 2 % voltage drop and 0.4 mH inductance are specified; for drive sizing, match the drive's continuous input current to this figure, not the 63 A ceiling. Total power loss sums to 99.8 W (77.3 W coil + 22.5 W iron core), which must be factored into the cabinet's thermal budget. The choke is recognized under EN 61558-2-20 and carries UL/CSA recognition — a key requirement for panels destined for North American or European markets. The 0.143 m depth, 0.219 m width, and 0.179 m height give a compact footprint for a 63 A three-phase reactor; verify backpanel space against these dimensions before laying out the gland plate.","metaTitle":"Siemens 4EP4000-3US00 Mains Choke, 63A, 690V, 3-Phase","metaDescription":"Siemens 4EP4000-3US00 mains choke for variable frequency drives. 3-phase, 690V AC, 63A max, 0.4mH.
