Additionally, it can be used for restricted earth-fault and residual earth-fault protection of generators, motors, transformers, and reactors.

Features

Compact design: Part of the Relion® 611 series with a withdrawable-unit design.
Simplified setup: Only application-specific parameters need to be set.
Communication: Supports IEC 61850, GOOSE messaging, PRP, HSR, and Modbus® protocols.
Flexibility: Configurable via local HMI, Web HMI, or PCM600 software.
