What are Phase Monitor Relays?

Phase Monitor RelaysPhase Monitor Relays provide protection against premature equipment failure caused by voltage faults on three-phase systems.

Depending on the unit selected, devices protect equipment against:

  • Phase Loss
  • Phase Reversal
  • Phase Unbalance
  • Undervoltage
  • Overvoltage

Common applications include:

  • Motors
  • Pumps
  • Compressors
  • Compactors
  • Process Equipment
  • Elevators
