REX615 is a freely configurable all-in-one protection and control relay

for power generation and distribution applications. 

A wide application coverage combined with a fully modular and scalable

hardware and software ensures maximum flexibility and optimal cost-effectivity

throughout the relay life cycle – from tailoring to adapting to changing and new application-specific

requirements.

REX615 represents the next step for ABB’s 615 and 620 series relays

in terms of technological innovation, flexibility, cost-effectiveness and standardization.

As part of ABB’s Relion® protection and control family of relays,

REX615 builds on ABB’s strong heritage of freely configurable multifunctional relays and many proven

protection algorithms.
