  • Features
  • Proprietary microcontroller based circuitry constantly monitors 3-phase voltage to protect against harmful line conditions, even before the motor is started
  • Advanced LED indication provides diagnostics which can be used for troubleshooting and to determine relay status
  • Adjustable trip and restart delay settings prevent nuisance tripping due to rapidly fluctuating power line conditions and allows staggered start up of multiple motors, after a fault, to prevent a low voltage condition
  • Combines protection and diagnostics
  • 2 to 30 s adjustable trip delta time at low and high voltage and unbalance
