Its 0.0083 H inductance with a 14 % relative throttling factor and 135 Hz resonant frequency targets harmonics from nonlinear loads. Rated reactive power of the filter bank is 10 kvar, so this reactor pairs naturally with a 10 kvar capacitor bank for a detuned filter assembly. Thermal class B (130 °C rise) per IEC 60085 gives you the winding temperature limit; keep the 40 °C ambient rating in mind when sizing the cabinet ventilation. This is a panel-mount component — screw-type and tab terminals for the main circuit, so you land power cables with ring lugs or fork terminals. The 0.219 m width and 0.179 m height take up a fair chunk of backplate real estate; the 0.143 m depth means it won't hit the enclosure door on a standard 300 mm deep cabinet, but check your gland-plate clearance. Three-phase in, three-phase out, no neutral connection needed. It's built to EN 61558-2-20 and carries UL/CSA recognition per the description line — that's the standard for reactors and small transformers, so it should pass a North American panel inspection without a fight. The screw terminals accept the lug sizes you'd expect for 13.9 A; tab terminals give you a quick-disconnect option if the panel builder prefers that. The lifecycle stage is marked mature — a stable, long-running catalog item, not a new release and not on the chopping block for EOL. No PCN or last-time-buy notice on record.","metaTitle":"Siemens SIDAC 4EP4000-8MS00 Filter Reactor, 13.9A, 400V","metaDescription":"Siemens SIDAC 4EP4000-8MS00 filter reactor, 3-phase, 13.9A rated, 400V, 50Hz, 14% throttling, IP00.
