Product Introduction
ABB REF615E-E is a feeder protection and control relay used in medium-voltage substations, industrial switchgear, and utility distribution panels where feeder selectivity, event recording, and IEC 61850 communication are required. The relay belongs to the Relion® 615 family and supports protection, control, monitoring, and automation within one compact platform.
Compared with older static or electromechanical feeder relays, this platform allows logic modification through PCM600 configuration tools instead of physical rewiring. Typical applications include cable feeders, overhead line feeders, backup protection, and ring-network distribution systems. Before installation, verify firmware revision, connectivity package version, and technical key compatibility against the existing project backup.
