Overview
The ABB REF630 is part of the Relion® 630 series, designed to provide comprehensive feeder protection and bay control for utility and industrial power networks. It supports radial, looped, and meshed distribution systems, with or without distributed generation. The REF630 is ideal for substations, switchgear, and feeder bays where reliability, flexibility, and interoperability are critical.
The REF630 offers advanced protection functions including overcurrent, earth fault, voltage protection, and breaker failure detection. It also provides built-in measurement, fault location, event logging, and disturbance recording, helping operators maintain system stability, reduce downtime, and improve fault response.
For instance, in a wind farm substation, the REF630 can monitor feeder currents and voltages, detect faults, and isolate affected sections to maintain continuous power delivery.
