AC Reactor Specifications
Reactors, both as input (line) and output (load) devices, protect adjustable frequency drives, motors,
and other load devices against excessive voltage and current.
The following guidelines may help determine input and output reactor requirements:
•
The following tables are only a guideline. The motor FLA should not exceed the reactor FLA.
• Install an input reactor if the power source is greater than 500 kVA.
• Install an output reactor if the distance between the drive and the motor exceeds 150 feet.
• Install an output reactor if a device, such as a power limit switch, is used to disconnect the motor
from the drive. Use a power limit switch early break circuit to fault the drive.
• Install one output reactor per drive for a multiple-drive arrangement requiring reactor protection.
• For a multiple drive arrangement, an input reactor for each drive is recommended for optimal
protection. However, if the drives are within two drive sizes of each other, a single input reactor
can be used. The reactor must be rated at amperage equal to or greater than the sum of the
amperage for all the drives.
• Reactors are most effective when the reactor current rating approaches the drive current rating.
