Product Introduction
Field crews know the pain when a feeder trips unexpectedly and the spare relay does not match the installed firmware or I/O map. The ABB REF615E_G HBFEAEAGNDA1ABA1XG solves that exact issue in medium voltage distribution systems.
This unit delivers non-directional overcurrent, directional earth-fault, and sensitive protection functions for overhead lines and cable feeders. In radial, looped, or meshed networks, it handles protection, control, measurement, and supervision tasks reliably. Typical applications include utility substations and industrial plants where fast fault clearing under 50 ms matters.
