Self or Dual Powered Three Phase and Earth Fault Overcurrent
MiCOM P12x is a range of directional and non-directional overcurrent relays from single phase/earth fault up to the multifunctional three-phase P127 device with voltage protection functions.
Housed in a compact 4U case in 20TE or 30TE widths, P12x is fully withdrawable to facilitate easy and quick replacement. The dual-rated current input is powered by conventional 1A or 5A Current Transformers. A wide-range power supply allows a flexible auxiliary voltage to be applied from 24-250Vdc/48-240Vac. P122 also offers a compact case solution with reduced hardware and functionality where installation space is minimal.
Software features include 2 settings groups for quick switching between application configurations and customisable reflex automation, allowing logical AND, OR or NOT gates.
P12x devices also include a rear RS485 communication port with a variety of protocols; DNP3, IEC 60870-5-103, Modbus and Courier.
