Rated for 400 V AC at 50 Hz, it carries a continuous AC current of 31.5 A (with a peak rating of 39 A) and provides 0.7 mH inductance per phase. AC maximum current 31.5 A, AC rated current 28.35 A. DC rated current 38.6 A. Coil loss 55 W, iron-core loss 9 W. Ambient temperature rating 40 °C. Thermal class B. This is a panel-mount component — no DIN rail, no enclosure, just an open-frame choke with screw terminals. The 0.178 m width, 0.153 m height, and 0.105 m depth mean it needs a flat mounting surface and clearance around the terminals for the screw-type connections (accepts up to the wire gauge that fits the terminal). IP00 means no protection against dust or moisture, so it must live inside a clean, dry cabinet or a ventilated enclosure. The three-phase connection is straightforward: line in, choke out to the converter, with the screw terminals taking the power wiring.","metaTitle":"Siemens 4EP3701-7DS00 Commutating Choke, 3-Phase 400V AC, 31","metaDescription":"Siemens 4EP3701-7DS00 commutating choke for converter, 3-phase, 400V AC, 31.5A max AC, 0.7 mH, IP00, screw terminals, 40°C ambient.
