Product Introduction
Direct technical positioning: The ABB REF615E-D is a dedicated feeder protection and control relay designed to protect, control, measure, and supervise overhead lines and cable feeders in utility and industrial power distribution systems.
This relay efficiently handles radial, looped, and meshed distribution networks regardless of distributed generation presence, supporting both unearthed and resistance/impedance grounded neutral systems. It stands out with 12 standard configurations for common feeder protection applications, IEC 61850 substation communication standard support including IEC 61850-9-2 LE process bus, and parallel redundancy protocols (PRP/HSR). You choose the REF615E-D when you need DNP 3.0, IEC 60870-5-103, and Modbus protocols alongside IEC 61850, with 48–250 Vdc auxiliary power and 3.0 kg compact weight for easy installation.
