Single Phase Panels – CBM

Single Phase Panels – CBM

One of the most critical situations in pump operation is dry running. In dry running situations a current decrease is detected. This reduction of consumed current is measured by the PS-R electronic relay fitted to the protection panel: When the preset undercurrent value is reached it switches the pump off.

Main Advantages:

  • Thermal memory that memorises heating and cooling cycles of the motor.
  • Automatic reset, adjustable from 2 to 240 minutes.
  • Indication of tripping cause.
  • Control point for pressure switch, buoy, programmer…
  • Includes: circuit breaker 1P+N, PS electronic relay, contactor, LED’s and on/off switch.


Protection against:

  • Dry running by monitoring undercurrent.
  • Overload with thermal memory.
  • Overvoltage (+ 15%) .
  • Short-circuit.
