The Siemens SIDAC 4EP3701-3US00 is a 3-phase output reactor rated for a maximum AC current of 6.1 A and a rated operational current of 5.5 A at 460 V. It covers a frequency range from 0 Hz to 120 Hz with a rated switching frequency of 3000 Hz. The reactor provides 0.0035 H inductance and is designed for ambient temperatures up to 40°C, with thermal class B insulation per IEC 60085.
Dimensions are 0.17 m wide, 0.15 m high, and 0.1 m deep. Connections are via screw-type terminals or tab terminals, which accept standard ring or fork lugs for the main power circuit.
Power loss splits into 49.6 W in the coil and 29.4 W in the iron core, totaling roughly 79 W of heat to dissipate inside the enclosure. The description references EN 61558-2-20 and UL/CSA recognition, so the reactor carries safety transformer and North American listing approvals.
