Schneider Electric PowerLogic™ MiCOM P121 Feeder Protection Relay

Schneider Electric PowerLogic™ MiCOM P121 Feeder Protection Relay provides dependable protection for medium-voltage distribution feeders where simple and effective fault protection remains a priority. The relay monitors feeder currents continuously and responds to overcurrent and earth fault conditions that can affect system reliability and equipment safety.

Many utilities and industrial facilities use the MiCOM P121 in feeder circuits that require straightforward protection without the complexity of advanced directional functions. Its numerical design delivers accurate fault detection while giving operators access to valuable operating and fault information.

The relay records events and disturbances that help maintenance teams identify the source of network problems and reduce troubleshooting time. Its compact footprint also makes installation easier in switchgear panels, distribution substations, and electrical control systems where panel space is limited.
