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 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. The REF615R is

a member of ABB’s Relion family and part of its 615 pro

tection and control product series. The 615 series IEDs

are characterized by their compact, withdrawable design.

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 substa

tion automation devices while providing Modbus® and DNP

simultaneously in one standard configuration.
