Rated for 460 V AC at 60 Hz, it carries a maximum continuous current of 65 A with a rated current of 58.5 A — the 58.5 A figure is the thermal design point for continuous duty at 40 °C ambient. Inductance is 0.00043 H. The 65 A maximum and 58.5 A rated current tell you the thermal limit: this choke can handle 65 A intermittently, but for continuous operation at 40 °C ambient you size it to the 58.5 A mark. At DC the rated current is 79.6 A — relevant if the choke is used in a DC bus application, though its primary role is AC line-side. Total power loss is 104.6 W (72 W coil + 32.6 W iron core). That heat must be dissipated; IP00 means no enclosure — it's an open-frame component for panel mounting with free air circulation. Thermal class B (130 °C insulation system) per IEC 60085 gives the winding temperature margin. Connections are flat-type terminals (bus-bar style), not screw or spring clamps. You'll need ring lugs or bus-bar taps sized for the 65 A path. ## Where It Goes — Deployment Context Width 0.219 m, height 0.179 m, depth 0.143 m. IP00 requires panel enclosure. Typical application: on the AC input of a variable-frequency drive (VFD) feeding a motor load — pump, fan, conveyor — where harmonic mitigation and inrush current limiting are needed. The 4% impedance is a common choice for general-purpose drive input reactors.","metaTitle":"Siemens 4EP4010-0BS00 Commutating Choke, 65A, 460V AC, 3-Pha","metaDescription":"Siemens 4EP4010-0BS00 commutating choke for converter, 3-phase, 460V AC, 65A max, 58.5A rated, 0.433mH, IP00.
