Product Introduction
User viewpoint (maintenance engineer): When replacing a feeder protection relay in a medium-voltage substation, you need the exact I/O configuration match. The ABB REF615E-1G HBFCACABAAC1ANN11G provides feeder protection and control for overhead lines and cable feeders in radial, looped, and meshed distribution networks.
This relay delivers directional and non-directional overcurrent and earth-fault protection, voltage/frequency/power-based measurement, and unique multi-frequency admittance-based earth-fault protection for higher sensitivity. It supports IEC 61850 Editions 1 and 2 with HSR/PRP redundancy, GOOSE messaging, and IEC 61850-9-2 LE for process bus applications requiring 4 μs time-stamping resolution. You choose this unit when your ordering code HBFCACABAAC1ANN11G matches your existing I/O needs and you need IEEE 1588 V2 Power Profile for substation-level Ethernet time synchronization.
