Industrial 3PR-0004C3H Three-Phase Line Reactor

Rex Power Magnetics 3PR-0004C3H is a three-phase line reactor rated for 4 A in a 480–600 VAC system, designed to be installed in series with variable-frequency drives and other power-electronic equipment to moderate switching transients and improve overall power quality. With 10.0 mH of inductance, it helps dampen inrush currents and harmonic content that can shorten motor life or cause voltage fluctuations, while the compact design keeps weight around 5 lb for convenient panel mounting. This Rex line reactor is cataloged as part of the company’s line reactor family and is commonly referenced by distributors for industrial applications requiring reliable current limiting and protection of drives, pumps, conveyors, and HVAC equipment. Note that Rex lists this specific model as discontinued by the manufacturer, so availability comes through secondary channels such as stock from authorized distributors, refurbished units, or remaining new-in-box inventory. Typical installations include motors, pumps, conveyors, compressors, and automated manufacturing lines where a 4 A, three-phase, 480–600 VAC line reactor can help smooth power delivery and reduce nuisance tripping or motor stress.
