Product Introduction
User perspective first — the ABB REF615E-1G HBFHAEAGNEA1BNN11G is a medium-voltage feeder protection relay tailored for industrial substations, utility networks, and switchgear retrofits. It integrates protection logic, event recording, breaker control, and IEC 61850 communication in a compact, withdrawable plug-in module.
Field experience shows this relay handles directional and non-directional overcurrent protection, earth-fault detection, breaker control, and PRP/HSR redundancy. In deployments with AC800M and MicroSCADA systems, engineers value its <20 ms trip response and real-time IEC 61850 GOOSE messaging for fault isolation. Lead time for verified stock is typically 2–3 weeks.
