1.3.1 AC Reactor Specifications
Reactors, both as input (line) and output (load) devices, protect variable frequency drives (VFD), 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 size of the reactor is based on motor HP.
• Install an input reactor if the power source is greater than 500 kVA.
• Install an output reactor if the distance between the VFD and the motor exceeds 150 feet (45.7 meters).
• Install an output reactor if a device, such as a power limit switch, is used to disconnect the motor from the VFD.
Use a power limit switch early break circuit to fault the VFD.
• Install one output reactor per VFD for a multiple-VFD arrangement requiring reactor protection.
• For a multiple VFD arrangement, an input reactor for each VFD is recommended for optimal protection.
However, if the VFDs are within two VFD 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 VFDs.
• Reactors are most effective when the reactor current rating approaches the VFD current rating.
