The 1321-3LR078-B AC Line Reactor is a three-phase line reactor from Allen-Bradley/Rockwell Automation. It belongs to the 1321 series of industrial power components. It has 380 to 480 Volts AC voltage, 78 Amps of current, 50/60 Hertz of frequency, and 1.00 mH of per phase inductance. This line reactor comes with an IP 00 open type of enclosure and it weighs 130 pounds. Its maximum torque is 5.65 N-m. When it is in the power regeneration mode, the line reactor can be used in front of an AC drive for DC bus circulating current. The 1321-3LR078-B AC Line Reactor helps to protect equipment from the input power disturbances that damage the drive, inverters, or other sensitive equipment.

The 1321-3LR078-B Line Reactor is an electro-magnetic device. It has a steel core wrapped with copper coils that form a magnetic field to limit the rising rate of the current and harmonics while absorbing power line disturbances. The line reactor ensures optimal performance in the presence of harmonics. It can be used on either the input or output of the drive for harmonic compensation. When selecting the suitable line reactor for an application, the motor Horsepower and voltage ratings must be considered. The 1321-3LR078-B Line Reactor can enhance the performance, efficiency, and life expectancy of motors and drives. It also reduces the impact of reflected waves in motor control applications with long leads. Verify that the drive and motor continuous current ratings are within the fundamental current rating of the line reactor before making a final selection of a line reactor. During installation, make sure to allow 152 millimeters (6.0 inches) of space on all sides for proper heat dissipation.
