Product Introduction
ABB REF620E_F NBFNAAAAABC1BNN1XF is a medium-voltage feeder protection and control relay designed for utility substations, industrial switchgear, and feeder automation systems. The relay belongs to ABB’s Relion 620E family and combines protection, monitoring, disturbance recording, and IEC 61850 communication in a withdrawable platform.
On retrofit projects, this relay is commonly used on 11–33 kV feeders where fast GOOSE communication and configurable logic are required. ABB REF620E_F NBFNAAAAABC1BNN1XF supports PCM600 engineering configuration and IEC 61850 process bus integration. Before installation, verify firmware revision, communication package, and technical key compatibility to reduce commissioning delays and configuration mismatch issues.
