Overview
The REU615 is part of ABB’s Relion® 615 series, offering a dedicated solution for voltage and frequency protection, load shedding, and voltage regulation. It is engineered for medium-voltage networks, including those with distributed energy resources (DERs). With its modular design and ready-made standard configurations, the REU615 ensures fast deployment and simplified engineering.
Moreover, the relay supports IEC 61850 communication, enabling seamless integration into digital substations and smart grid environments. In addition, its built-in HMI, programmable logic, and extensive event recording capabilities make it a powerful tool for both protection and control. Therefore, it is widely used in substations, industrial plants, and renewable energy systems.
