FU), 3-phase, 460V AC, 31.5A rated / 35A max, 1 mH inductance, 5% inductive drop, IP00, screw terminals, thermal class B.","salesMarkdown":"The Siemens 4EP4000-2BK00 is a 3-phase mains choke — what the Germans call a Netzdrossel für Frequenzumrichter — sized for a 31.5 A continuous load on a 460 V AC line, with a 35 A thermal maximum at 40 °C ambient. That 1 mH inductance with a 5 % inductive voltage drop is tuned to knock the edge off the harmonics a variable-frequency drive throws back at the supply, protecting upstream contactors and transformers from the high-frequency trash. IP00 means it's an open-frame component for inside a cabinet, not a standalone box; plan on the screw terminals for the main circuit connections. The 31.5 A rated current and 35 A maximum tell you this choke is meant for a drive in the 15–22 kW range on a 460 V supply, depending on the drive's input current draw. The 5 % inductive drop is a standard value for line reactors — it's enough to limit harmonic distortion without dragging the DC bus voltage down too far. Thermal class B means the winding insulation is rated for 130 °C hot-spot, which is the common industrial floor; nothing exotic, but adequate for a 40 °C ambient cabinet. This part carries a 'mature' lifecycle stage — Siemens' way of saying it's an established, stable product that's not in active phase-out but also not the newest thing on the shelf. The IP00 open-frame construction and screw terminals are straightforward to wire, but the footprint — 0.219 m wide, 0.179 m tall, 0.143 m deep — needs to be checked against your panel layout before committing.","metaTitle":"Siemens 4EP4000-2BK00 Mains Choke, 31.5A 460V 3-Phase","metaDescription":"Siemens 4EP4000-2BK00 mains choke for VFD, 31.5A rated, 460V AC, 3-phase, 5% inductive drop.
