Motor Protection Device



  • Motor Protection Device is a complete and economic solution to protect motor
  • Instantly indicates the exact Fault-Value(Amps)-Phase
  • Saves cost on Production Loss, Motor Loss and Time spent on Fault identification
  • Our Relay Provides different curves for accurate tripping on the bases of starting time current of the motor
  • Digital Ameter with auto scanner for three phase Current & Earth Leakage Current
  • CT Specially designed for Motor Protection
  • Man-Machine Interface through keypad & Display
  • Annunciation indicates the type of fault
  • In built Hour Counter which records Motor Running Hours
