Multi-protection relay (Sequence-Failure-Under& over relay)

$ 36.80

Product Description

  • Microcontroller based.
  • True RMS measurement
  • Select 3phase 3wire or 3phase 4wire mode by a knob.
  • N phase failure protection for 3phase 4 wire
  • 1NO+1NC output-8A
  • LED indication for supply and output state
  • 1 module Din-rail mounting

Applications:

  • Three phase voltage monitoring relay is used to protect the three-phase electric motors supplied from three-phase mains, against phase failure, incorrect phase sequence, voltage asymmetry, over and under voltage.
  • User can select three phase three wire or three phase four wire mode as required
