Feeder protection relay REF615R

The most powerful, advanced, and simplest feeder protection relay in its class

REF615R is a dedicated feeder relay, perfectly aligned for protection, control, measurement, and supervision of utility substations and industrial power systems. The 19 inch rack mount form of ABB’s Relion® REF615 utilizes the same form and fit as the DPU2000R relay and provides exact wire-alike matching rear terminals, making the REF615R the ideal solution for upgrading to the industry’s latest technologies. Engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices while providing Modbus and DNP simultaneously in one standard configuration.
