Description
Allen Bradley 1321-3R8-B Line Reactor 8A 3mH 3-Phase 600V 20kHz Part 150134
The Allen-Bradley 1321-3R8-B is a three-phase AC line reactor rated at 8 amps and 3 millihenries of inductance, designed for use with variable frequency drives (VFDs) and variable speed drive systems. It connects in series on the AC input or output of a drive to limit current inrush, reduce harmonic distortion, and protect drive electronics from line voltage transients and switching spikes. The unit features an open-frame, panel-mount construction with a three-core wound coil assembly and a screw-terminal wiring block.

Applications
Three-phase AC line reactors like the Allen-Bradley 1321 series are standard protection components in industrial drive systems. They are installed on the AC input side of variable frequency drives (VFDs), soft starters, and servo drives to limit inrush current at startup, reduce total harmonic distortion (THD) fed back onto the supply line, and protect sensitive drive electronics from power line transients, voltage notching, and switching noise generated by IGBT inverter stages. The 1321-3R8-B is sized for smaller drive systems — typically 1–3 HP drives at 460–600V, three-phase — and is commonly used in conveyors, pumps, fans, compressors, and other motor-driven industrial machinery. Allen-Bradley 1321 series reactors are designed to work with the full range of Rockwell Automation PowerFlex variable speed drives and remain a current, widely specified component in industrial automation and motion control installations.
This Allen-Bradley 1321-3R8-B 3-Phase Line Reactor has been inspected and is in good used condition. It was pulled from a working environment where it was previously in active service. The coil windings and terminal block appear clean and intact. The mounting base shows some light surface oxidation consistent with normal industrial use, and the lead wires are present and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
