Description

The great advantage of the P Relay is that, without requiring any external detectors such as level electrodes, it monitors the load of the motor and stops it before an expensive breakdown occurs. Ex. when a water well is dry, the relay stops the motor by undercurrent without the need of a level sensor.

Features

  • Suitable where the undercurrent (running without load) is critical.
  • Does not require level sensors to detect dry running.
  • For three phase motors from 1 to 630 A and over*.
  • Cable feed through.
  • Precise motor heating and memory, reproduces its thermal image.
  • Visual indication of tripping cause.
  • Manual, remote and automatic reset.

Applications

  • Some typical applications in Residential, industrial, and agricultural installations as follow:
  • Submersible pumps: water supply, irrigation, well dewatering, petrol stations…
  • Surface pumps: sewage treatment plants, swimming pools, pressure sets, fire-fighting equipment, ...
  • Other applications where it is critical to avoid operation at no load: belt drives, ventilators, conveyor belts…

Protection functions

  • Overload.
  • Undercurrent.
  • Phase imbalance or phase loss.
  • Phase sequence.
