Product Introduction
ABB REF620 NBFNAAAAABC1BNN1XF is a medium-voltage feeder protection and control relay deployed in industrial substations and utility distribution feeders. It is part of ABB’s Relion 620 series, combining protection, control, measurement, and IEC 61850 communication inside a withdrawable IED platform.
In field applications, this relay is commonly used on 11–33 kV feeders that require selective tripping, disturbance logging, and fast GOOSE signaling. Configuration and logic programming are handled through ABB PCM600. Before installation, firmware, I/O configuration, and technical key verification are essential to prevent commissioning delays, even if the hardware is fully functional.
