Product Description

Schneider Micom P127 relay is part of MiCOM P12x, a range of directional and non-directional overcurrent relays from single phase or earth fault up to the multifunctional three-phase P127 numerical relay with voltage protection functions. Models available: MiCOM P120, MiCOM P121, MiCOM P122, MiCOM P123, MiCOM P125, MiCOM P126, MiCOM P127

MiCOM P127 is housed in a compact 4U case in 20TE or 30TE widths, Schneider P127 Relay 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.

MiCOM P127 devices also include a rear RS485 communication port with a variety of protocols; DNP3, IEC 60870-5-103, Modbus and Courier.
