Allen-Bradley 1321-3R1-D Line Reactor

The Allen-Bradley 1321-3R1-D (1321-3R1-D) is a line reactor engineered for industrial drive systems and power conversion equipment. Operating as an inductive filter component, this reactor is designed to suppress electrical noise, attenuate harmonic distortion, and absorb transient voltage surges before they reach sensitive motor drives or connected automation devices. Integrating this unit into the electrical power circuit helps smooth incoming line current, reduce peak currents, and protect variable frequency drives and power electronics from adverse electrical mains disturbances. The unit has a net weight of 10 kg, reflecting its robust construction designed for installation inside industrial control enclosures and drive cabinets. It is suited for demanding industrial automation workflows, manufacturing plants, and processing machinery where stable power quality and equipment longevity are essential. By mitigating supply line transients and dampening harmonics, the reactor supports system reliability and minimizes the risk of premature failure in motor control applications.
