Single phase by Undercurrent – PS-R

Single phase by Undercurrent – PS-R

Without requiring any external detectors like level electrodes, it monitors the load of the motor and stops it before an expensive breakdorwn occurs.

  • Without requiring level sensor to detect dry running.
  • For single phase motors from 3 to 16 A and over. Cable feed through.
  • Precise motor heating and cooling memory, reproduces its thermal image.
  • Visual indication of tripping cause.
  • Adjustable reset time for I<.
