MiCOM P11x

Self or Dual Powered Three Phase and Earth Fault Overcurrent


MiCOM P11x
  • Features

    MiCOM P11x relays are a compact solution for all MV applications where overcurrent and/or earth-fault protection are required. It caters for applications with conventional auxiliary power and where auxiliary voltage is not available or not guaranteed by using innovative Self-Power or Dual-Power modes ( P116).

    Flexible and compact options for the mounting of the device means that P11x can be applied using Flush, Panel, Wall, DIN Rail or Withdrawable techniques.

    All devices include digital inputs and outputs and an inbuilt USB port for fast connection to setting software (MiCOM S1 Studio).

    MiCOM P11x relays include many additional model specific features, dedicated to their intended purpose, such as:

    Recording of faults, events and disturbances
    RS485 communication ports
    Capacitive discharge output (sensitive trip coils, strikers and flags available in the 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
