Rex Power Magnets 3PR-0004C3H Three-Phase Reactor

Rex Power Magnetics 3PR-0004C3H is a three-phase line/load reactor designed to be installed in series with motor drives and other power‑electronic equipment to tame voltage and current transients. Built for VFDs and similar non‑linear loads, it helps improve power quality and protect equipment by limiting harmonic currents and inrush, contributing to longer system life. This air‑cooled, copper‑wound reactor supports Rex’s three‑phase line reactors across a broad range of service conditions: a maximum voltage rating of 600 V, operation at 60 Hz with 50/60 Hz options, and an indoor Type 1 enclosure for general indoor installations. The product family lists capacities from 2 A up to 1,250 A in three‑phase configurations, with an insulation system rated to 220°C (150°C temperature rise max), audible sound levels typically below 40 dBA, overload capability of 150% of rated current for 1 minute, and a saturation level not less than 250% of rated current (with at least 50% of rated inductance at 350% rated current). The 3PR‑0004C3H model is a specific line in this Rex Power Magnetics line of line reactors and is intended for use on either the line side or the load side of VFDs and other power‑electronics in industrial and commercial settings.
