Overview

The Hammond Power CRX74D4NE enclosed reactor delivers precise current control and stable inductance for industrial power systems. Designed for motor drives, power conversion systems, and harmonic filtering, it ensures system stability and efficiency in demanding electrical environments. The reactor features continuous copper windings with brazed, welded, or bolted terminations, vacuum pressure impregnated polyester resin insulation, and a dielectric strength of 4000 volts RMS. Temperature rise is rated at 180°C (115°C rise) for operation above 40 Amps at 50°C ambient, complying with NEMA ST20-2014 altitude de-rating standards. With dimensions of 8.00" deep, 8.13" high, and 10.00" wide, the CRX74D4NE fits standard control panels while maintaining a compact footprint. Its 3% to 5% impedance rating ensures stable operation across variable load conditions, making it ideal for applications requiring precise current regulation and minimal harmonic distortion.
