The thermal class is B per IEC 60085, with a 40°C ambient rating. Copper losses (coil) are 53 W, iron losses 9 W — total 62 W dissipated in free air. The IP00 enclosure means it's an open-frame component for cabinet mounting; no washdown or dust protection, so panel ventilation must handle the heat. Dimensions are 0.178 m wide, 0.153 m high, 0.105 m deep — a compact footprint for a 25 A three-phase choke. Main circuit connections are screw-type terminals, which simplifies panel wiring with ring or fork lugs. No DIN-rail clip; it's a foot-mount chassis unit that bolts to the panel backplate.","metaTitle":"Siemens 4EP3701-5DS00 Commutating Choke, 25A AC, 400V, 0.89m","metaDescription":"Siemens 4EP3701-5DS00 commutating choke for converter applications.
