ABB REU615 Protection Control Relay for Voltage Monitoring
Description
TheREU615is part of ABB’sRelion® 615 series, offering a dedicated solution for voltage and frequency protection, load shedding, and voltage regulation. It is engineered formedium-voltage networks, including those withdistributed energy resources (DERs). With its modular design and ready-made standard configurations, theREU615ensures fast deployment and simplified engineering. Moreover, the relay supportsIEC 61850 communication, enabling seamless integration intodigital substationsandsmart grid environments. In addition, its built-inHMI,programmable logic, and extensiveevent recording capabilitiesmake it a powerful tool for both protection and control. Therefore, it is widely used insubstations,industrial plants, andrenewable energy systems.
