Allen-Bradley 1321-3R25-B Line Reactor

The Allen-Bradley 1321-3R25-B (1321-3R25-B) is a line reactor designed for power conditioning and electrical protection in industrial drive and automation systems. Operating within motor control circuits and variable frequency drive installations, this unit serves to absorb electrical line disturbances, mitigate transient voltage spikes, and buffer incoming line noise. By providing inductive reactance between the incoming power supply and connected drives, the line reactor helps protect sensitive power semiconductors, smooth input current waveforms, and decrease nuisance tripping caused by power line fluctuations. Built for dependable integration into industrial control panels, the 1321-3R25-B features a solid construction with a net weight of 10 kg. It is typically deployed across manufacturing lines, material handling equipment, pumping stations, and industrial processing machinery where drive reliability and system stability are essential. Installing this genuine Allen-Bradley line reactor ensures compatibility with designated power equipment, supporting continuous plant operations and providing a straightforward replacement during planned maintenance, system retrofits, or service overhauls.
