Application

The REF615R provides main protection for overhead lines,

cable feeders, and busbar systems of distribution substations.

It can be applied for protection and control of grounded and

ungrounded distribution systems.

One configuration tailored to meet and exceed these DPU2000R

ANSI and IEC configurations:

− Standard:  587R… (ANSI); 687R…(IEC)

− Synch Check:  587C…(ANSI); 687C…(IEC)

− SEF:  587E…(ANSI); 687E…(IEC)

The REF615R is a dedicated feeder IED perfectly aligned

for the protection, control, measurement, and supervi

sion of utility substations and industrial power systems.

The REF615R is designed for users looking for a 19” rack

mount form of ABB’s Relion® REF615. The REF615R utilizes

the same form and fit as the DPU2000R relay and provides

exact wire-alike matching rear terminals. This wire-alike

feature makes the REF615R the ideal solution for upgrad

ing to the industry’s latest technologies.
