Product Introduction
Direct technical positioning: The ABB REF615E-D is a dedicated feeder protection and control relay for protection, control, measurement, and supervision of overhead lines and cable feeders in utility and industrial power distribution systems.
It handles radial, looped, and meshed distribution networks with or without distributed generation, featuring directional/non-directional overcurrent and earth-fault protection, voltage/frequency/power-based functions, and multi-frequency admittance-based earth-fault protection for higher sensitivity and selectivity. You choose the REF615E-D when you need optional advanced fault location, arc protection, high-speed outputs, and IEC 61850 process bus support without extra wiring. Power draw stays under 10 W, and the unit accepts both 1 A and 5 A CT secondaries programmable in software.
