Pump Protection Relay – LP1

$37.79

Microprocessor based pump protection relay capable of protecting a submersible pump against all major power line faults. The unit calibrates itself under normal running conditions and stores these parameters in non-volatile memory. The unit also incorporates a reset delay for under current situations to enable the borehole to replenish itself. In an over current situation the unit will retry three times to prevent permanent tripping with temporary blockages.

 

Features:

 

  • Microprocessor based protection relay
  • Over / Under Current Protection
  • Over / Under Voltage Protection
  • Three retries for Over Current
  • Automatic Self Diagnosis of Pump
  • LED indication for all faults
