  • Incorporated with surge arresters to protect the pumping system from high voltage surges
  • Technically advanced, highly sensitive pump protection relay (PPR) enables immediate tripping of power supply in overload and under load conditions
  • Protects the pumpsets against dry running by sensing the current
  • Protects against phase failure and phase imbalance conditions
  • Control panels with PPR, comprises of auto start provision and phase sequence protection I An option for float switch is provided in the control panel with PPR, for the automatic operation of the pumpset based on water level
  • Provision of Ammeter and Voltmeter to check the Voltage & Current (in specific models only)
  • Attractive powder coated sheet metal enclosure


  • These control panels can be used to control and protect all kinds of prime movers especially submersible motors, Centrifugal pumps etc, used for various applications.
