Product Introduction
Comparison vs. sibling model: The ABB REF615E-1G HBFFAEAGNBA1BAA11G differs from directional variants (like HBFCACABNBA1BNN11G) by delivering non-directional overcurrent and non-directional earth-fault protection instead.
This relay handles protection, control, measurement, and supervision of overhead lines and cable feeders in radial, looped, and meshed distribution networks with or without distributed generation. It supports IEC 61850 Editions 1 and 2 including HSR/PRP redundancy and GOOSE messaging, plus IEC 61850-9-2 LE for process bus applications requiring 4 μs time-stamping resolution. You choose HBFFAEAGNBA1BAA11G when you need non-directional protection (functional application B), 4 analog current inputs plus 5 voltage inputs, 12 binary inputs with 6 binary outputs, and Modbus serial communication alongside IEC 61850 Ethernet.
