FU), 3-phase, 460V AC, 60Hz, 116A rated / 129A max, 0.27mH, 5% voltage drop, IP00, thermal class H, flat-type terminals.","salesMarkdown":"The Siemens 4EU2722-0FH00-0AA0 is a three-phase mains choke (line reactor) designed for installation ahead of a variable-frequency drive (VFD). It smooths the input current waveform, reduces harmonic distortion, and limits inrush current — which keeps upstream breakers from nuisance-tripping and extends the drive's DC-bus capacitor life. This is an open-frame (IP00) component — no enclosure, no finger-safe cover. It belongs inside a cabinet, bolted to a mounting plate or chassis. The 0.208 m depth, 0.27 m width, and 0.248 m height define the panel footprint; plan for clearance around the flat-type terminals for lug access. Thermal class H insulation means the winding can handle a 180 °C hot-spot temperature, so it coexists with other heat sources in a crowded enclosure as long as the ambient stays at or below 40 °C. The 116 A rated current is the continuous thermal rating at 40 °C ambient — size your drive's input current to stay at or below this number for normal operation. The 129 A maximum is the overload headroom, not a steady-state figure; it covers the brief inrush when the drive's DC bus charges. The 5 % voltage drop is the standard impedance for a drive input reactor — high enough to attenuate harmonics and limit fault current, low enough to avoid sagging the drive's DC bus under load. The 0.27 mH inductance paired with 460 V / 60 Hz gives the impedance that produces that 5 % drop; if your line frequency is 50 Hz instead of 60 Hz, the reactor's impedance drops and the voltage drop percentage changes — verify compatibility if your site runs 50 Hz.","metaTitle":"Siemens 4EU2722-0FH00-0AA0 Mains Choke, 116A/460V/60Hz","metaDescription":"Siemens 4EU2722-0FH00-0AA0 mains choke for VFD, 3-phase, 116A rated, 460V, 60Hz, 0.27mH, IP00, thermal class H.
