It is designed for AC motor drive output circuits to limit the rate of voltage rise (dV/dt) and reduce reflected-wave overvoltage on long cable runs — a common cause of premature motor insulation failure in variable-frequency drive installations. Thermal class B with rated ambient 40°C, dissipating 44 W in the coil and 22 W in the iron core at full load. 18 A maximum current is the continuous thermal rating at 40°C ambient, carrying load without exceeding class B temperature rise. 8 kHz switching frequency matches the carrier frequency of many IGBT-based drives. The screw-type terminals accept standard ring or fork lugs for the main circuit connections. Dimensions are 0.17 m wide by 0.15 m tall by 0.1 m deep — a compact footprint for a 3-phase 18 A reactor, but verify panel clearance for the magnetic field and heat dissipation around the core. Mount on a flat metal panel inside the enclosure — IP00 requires the panel to provide the environmental seal. Screw terminals accept conductors sized for 18 A continuous.","metaTitle":"Siemens SIDAC 4EP3705-7DS00 Output Reactor, 18A 3-Phase 8kHz","metaDescription":"Siemens SIDAC 4EP3705-7DS00 output reactor, 3-phase AC, 18A max, 8kHz switching frequency, 0.5mH inductance, IP00, screw terminals.
