Allen-Bradley 1321-3R500-A Line Reactor

The Allen-Bradley 1321-3R500-A (1321-3R500-A) is a line reactor engineered for power conditioning and drive protection in industrial automation environments. Built for integration with variable frequency drives and power conversion systems, this Bulletin 1321 component acts as an inductive filter between the electrical power source and connected motor control equipment. It functions by absorbing line transients, dampening voltage spikes, reducing harmonic distortion, and minimizing nuisance tripping caused by power disturbances across the industrial distribution network. By attenuating current surges and high-frequency noise, the 1321-3R500-A line reactor helps prolong the operating lifespan of motor drives and connected electrical components. It provides dependable performance in demanding manufacturing, material handling, processing, and machinery control applications. Weighing approximately 10 kg, this unit is built for sturdy mounting inside industrial control cabinets and electrical enclosures. It serves as an essential component in preventative maintenance, system retrofits, and direct replacement workflows where reliable power filtering and robust drive protection are required.
