Stromrichter) designed for line-side or load-side use with converter drives. It carries a rated operating voltage of 400 V AC at 50 Hz and delivers a maximum continuous AC current of 35.5 A, with a peak current capability of 44 A. The rated inductance is 0.62 mH, with a relative inductive voltage drop of 4% at rated current and frequency — a standard figure for smoothing commutation notches and limiting di/dt on the converter input. The choke is rated for an ambient temperature of 40 °C and conforms to thermal class B per IEC 60085, meaning the insulation system withstands a 130 °C hot-spot temperature — adequate for general-purpose industrial enclosures without forced cooling. Total power loss splits into 55 W in the coil and 9 W in the iron core at rated load, a figure to consider for enclosure heat budgeting. Dimensions are 0.178 m wide, 0.153 m high, and 0.105 m deep. The design is recognized under UL/CSA per EN 61558-2-20, so it meets the common North American and European safety standards for isolating and safety transformers — relevant for panel builders exporting equipment.","metaTitle":"Siemens 4EP3701-8DS00 Commutating Choke, 400V 35.5A AC","metaDescription":"Siemens 4EP3701-8DS00 3-phase commutating choke for converters.
