Product Introduction
ABB REF620E_1G is a medium-voltage feeder protection and control relay deployed in substations, industrial power distribution, and utility feeder networks. It belongs to ABB’s Relion 620E family, integrating protection, supervision, IEC 61850 communication, and disturbance recording in a withdrawable platform.
In field deployments, this unit is often used for 11–33 kV feeders where fast GOOSE messaging, configurable protection logic, and disturbance logging are required. ABB REF620E_1G supports PCM600 configuration for logic changes without hardware rewiring. Firmware revision and I/O configuration must be verified before replacement to prevent commissioning issues.
