Product Introduction
Data-led positioning: The ABB REF615E-1G delivers feeder protection with 4 μs time-stamping resolution for process bus applications, supporting IEC 61850-9-2 LE and IEEE 1588 V2 in a compact drawout design.
This relay protects overhead lines and cable feeders in radial, looped, and meshed distribution networks up to 36 kV, featuring directional/non-directional overcurrent, earth fault, thermal overload, and optional arc-flash detection. You choose it when you need six setting groups, high-speed (< 1 ms) outputs, and cable fault detection (CFD) without adding dedicated CTs or wiring. Typical power consumption stays under 16 W, and the unit accepts 1 A or 5 A CT secondaries programmable in software.
