Product details

Commutating Choke for Converter Duty

The Siemens 4EP3702-1DS00 is a three-phase commutating choke (line reactor) designed for converter input circuits, rated at 500 VAC and 50 Hz. It handles a maximum continuous current of 22.4 A, with a rated current of 20.16 A and a peak current capability of 28 A. The 1.3 mH inductance limits current rise and harmonics on the line side of a variable-frequency drive or rectifier.

Electrical and Thermal Ratings

The DC-rated current is 27.4 A, useful for applications where the converter draws a DC-link component. Total power loss is 52.58 W in the coil plus 9.3 W in the iron core at rated conditions, and the thermal class is B (130 °C rise per IEC 60085). Ambient temperature rating is 40 °C.

Enclosure and Termination

Protection class is IP00 — open-frame construction intended for installation inside a cabinet or enclosure that provides the environmental seal. The main current circuit terminates via screw-type terminals, which accept standard power conductors for panel wiring. Dimensions are 0.178 m wide, 0.153 m high, and 0.105 m deep.
