The 1321-3RB250-B line reactor is a three-phase input/output line reactor from Allen-Bradley. It comes with open style enclosure and flag type terminals. The fundamental amperage rating of the 1321-3RB250-B line reactor is 250 Amps. it has 0.09 mH of inductance based on fundamental Amps. The inductance tolerance rating is +/-10%. This line reactor module assures equipment durability by absorbing power line disturbances such as spikes, sags, and transients. It also helps to protect the drive from spurious tripping and damage. Allen-Bradley line reactors can be applied on both the input and output sides of the host drives. The line reactor, which is on the input side, protects the drive from surges or spikes on the incoming power line by reducing harmonic distortion. Connecting a load reactor at the output of the drive protects the drive by reducing the surge current, motor output voltage (DV/DT), motor temperature, and motor terminal peak voltage.
When multiple motors are controlled by one drive, the 1321-3RB250-B line reactor can be located between the drive and all the motors. This 3-phase line reactor can be used for single-phase applications by leaving the center coil disconnected. The 1321-3RB250-B line reactors are supplied with front-facing copper tabs for cable connections. It has 20 kHz maximum frequency. The fundamental frequency for Line/Load is 50/60 Hertz. The maximum ambient temperature for this type of line reactor is 50 degrees Celsius. The maximum input rated voltage is 600 Volts AC. It has 231 Watts of heat dissipation. Its approximate weight is 36.3/80 kilograms. When selecting the reactor, make sure to verify that the drive and motor continuous current rating is within the fundamental current rating of the reactor (250 Amps).
