Product Introduction
ABB REF620-5BFNAAAANHC8BNL11G is a feeder protection and control relay used in medium-voltage substations, industrial distribution panels, and utility feeder automation systems. The relay integrates protection, supervision, fault recording, and IEC 61850 communication inside ABB’s Relion 620 platform.
A common deployment is 11–33 kV feeder protection where fast GOOSE messaging, disturbance recording, and configurable logic are required. ABB REF620-5BFNAAAANHC8BNL11G supports radial, looped, and meshed networks, including systems with distributed generation such as solar or wind interconnections. Before installation, verify firmware revision, technical key, and PCM600 connectivity package compatibility to avoid commissioning delays.
