REF630 ABB Feeder Protection Control Panel for Medium Voltage Systems

Description

TheABB REF630is part of theRelion® 630 series, designed to providecomprehensive feeder protection and bay controlfor utility and industrial power networks. It supportsradial, looped, and meshed distribution systems, with or without distributed generation. The REF630 is ideal forsubstations, switchgear, and feeder bayswherereliability, flexibility, and interoperabilityare critical. The REF630 offersadvanced protection functionsincluding overcurrent, earth fault, voltage protection, and breaker failure detection. It also providesbuilt-in measurement, fault location, event logging, and disturbance recording, helping operators maintain system stability, reduce downtime, and improve fault response. For instance, in awind farm substation, the REF630 can monitor feeder currents and voltages, detect faults, and isolate affected sections to maintaincontinuous power delivery.
