Allen-Bradley 1321-3R55-C Line Reactor

The Allen-Bradley 1321-3R55-C (1321-3R55-C) is a line reactor designed for use in industrial drive systems and motor control applications. Operating within compatible variable frequency drive assemblies and electrical power architectures, this unit provides inductive filtering on the power line to help absorb line disturbances, suppress electrical transients, and reduce harmonic distortion. Installing line reactors ahead of drive equipment helps protect internal drive components, enhances overall system reliability, and reduces nuisance tripping caused by power line fluctuations. With an approximate net weight of 10 kg, the 1321-3R55-C offers robust construction suitable for control cabinet mounting and demanding manufacturing environments. It serves as an essential component in routine maintenance, equipment upgrades, and replacement tasks across automated production machinery, motor control centers, and continuous processing facilities. By conditioning the input power feed, it promotes stable operational performance and extends the operating life of downstream drive electronics in industrial automation installations.
