MiCOM P11x

Self or Dual Powered Three Phase and Ground Fault Overcurrent Protective Relays

MiCOM P11x relays are a compact solution for all MV applications where phase and ground fault protection is required. Ideally suited for applications where conventional power supply auxiliary voltage may not be available by using an innovative Self-Power or Dual-Power mode (P115 and P116).

MiCOM P11x
  • Features

    • The P116 relay includes fuse curves that allows it to become a switch controller that can coordinate with existing fused devices.
    • The P116 can be ordered with both Modbus RTU and DNP 3.0 RTU communications protocols.
    • The P116 relay features Individual Phase Trip Indicators for quick situational analysis
    • Recording of faults, events and disturbances
    • RS485 communication ports
    • Capacitive discharge output (sensitive trip coils, strikers and flags available in P115 and P116)
    • Selectable measuring criteria: True RMS or fundamental frequency current measurements
    • Conventional CT inputs or Extremely compact solution using dedicated LV Phase Ring Core CTs

    Contractual warranty
    Period : 2 years
