The IP00 open-frame construction means it mounts inside an enclosure; the screw-type and tab terminals accept lug or ring-tongue terminations. The 14 A maximum current is the thermal limit at 40 °C ambient, thermal class B (130 °C winding rise). That 14 A figure governs the drive it pairs with — match it to a drive whose rated output current does not exceed 14 A at the switching frequency. The 8 kHz rated frequency is the design point for the core; running at a significantly different switching frequency will shift the saturation margin and losses. Total power loss breaks down as 37 W in the coil (copper) and 20.5 W in the iron core, for a combined 57.5 W at full load. That heat must be removed from the enclosure — plan for forced ventilation if the panel is sealed. Dimensions are 0.17 m wide by 0.15 m tall by 0.1 m deep. The footprint is compact for a 14 A three-phase reactor, but the IP00 chassis requires a minimum clearance to grounded metal per the drive manufacturer's guidelines.","metaTitle":"Siemens SIDAC 4EP3705-8DS00 Output Reactor, 14A 3-Phase 8kHz","metaDescription":"Siemens SIDAC 4EP3705-8DS00 output reactor, 14A max, 3-phase AC, 8 kHz rated frequency, 0.3 mH inductance, IP00.
