The ABB REF615E is an enhanced version of the ABB Relion® 615 series, designed for intelligent feeder protection, control, measurement, and monitoring in medium-voltage distribution systems.
As part of ABB’s next-generation digital protection platform, REF615E delivers improved flexibility, stronger communication capabilities, and advanced protection logic compared to earlier 615 configurations. It is widely deployed in utility substations, industrial power systems, and smart grid applications where fast fault response and high system reliability are critical.
The “E” (Enhanced) version focuses on expanded functionality, better integration options, and optimized lifecycle performance, making it a preferred solution for modern IEC 61850-based automation environments.
