REX610 released – all-in-one protection for basic power distribution applications

2022-09-15 - Release announcement

We are happy to announce the release of the all-in-one protection and control relay REX610, the latest addition to ABB’s Relion® product family. Packed with innovative simplicity, REX610 provides optimal protection for any basic power distribution application. 

With only six variants it is easy to order, set up, use and service – and to keep in store. It is a pure plug-and-play solution with installed hardware modules unlocking all available functionality. The fully modular hardware, together with an extensive range of default functionality and access to new developments via firmware updates, allow easy and flexible customization, modification and adaptation to changing protection, communication and network requirements, at any time. This makes REX610 a flexible, cost-effective and sustainable choice – futureproofed for the evolving grid.

With more than 700,000 SPACOM relays installed worldwide, dating back to the 1980’s, the Relay Retrofit Program for SPACOM to REX610 offers an excellent way to easily modernize the protection and control system. A convenient tailor-made retrofit adapter set allows quick and easy replacement of selected SPACOM relay types with REX610 relays. The result is extended switchgear lifetime, full availability of relay life cycle services, and the possibility to adapt the power protection system to meet future requirements.
