Product description

The Allen-Bradley 1321-3R18-C is a 3-phase line reactor designed to absorb power line disturbances and protect variable speed drives. It features an inductance of 2.5 mH and an impedance rating of 3-5%, with a current rating of 18 Amps. This reactor operates within a voltage range of 200 to 690 VAC, providing essential harmonic compensation and IGBT protection.

This line reactor is crucial for enhancing the longevity and performance of industrial equipment by mitigating issues like voltage spikes and current surges. It helps prevent spurious tripping of drives and circuit breakers, ensuring smoother operation in demanding applications. Its open enclosure (IP00) is suitable for installation within control panels.
