True RMS current and frequency values are measured by all the MiCOM P12x relays.
The LEDs and LCD display on the front panel are fully programmable to user requirements. MiCOM P12x relays provide simple and powerful operator interface. Flexible automation functions enable accurate co-ordination with other devices. Protection features of the MiCOM P12x range include 3 independent phase overcurrent stages, 3 independent earth overcurrent stages, 12 selectable curve characteristics, thermal overload protection, undercurrent and negative-sequence overcurrent protection. Starting with the single phase P120 up to the multifunction three phases and earth P123, MiCOM relays are fully designed to protect and control industrial plants, utilities substations and networks at any voltage level. The MiCOM P12x series are the universal overcurrent relay range for ALSTOM.
