ABB Expands Its Relion® ANSI Portfolio to Include Single-function Protection Relays

The REF601, REJ601 and REM601 are members of ABB’s Relion® protection and control product family and its 605 series. The relay provides an optimised composition of protection, monitoring and control functionality in one unit, with the best performance usability in its class.

Houston, Texas, – ABB, the leading power and automation technology group, today announced the release of three additions to the ABB Relion® product family as part of its 605 protection and control series for the ANSI market.

The Relion 605 series of Protection Relays is now available for North America and for both ANSI and IEC markets. This launch extends the Relion portfolio with a basic, user-friendly relay series that can be configured without a programming tool. The 605 series relays – REF601, REJ601, and REM601 – designs for Feeder, Overcurrent, and Motor protection respectively, will offer the best value in digital protection for low to mid-range distribution applications.

This new release of Relion 605 series distribution protective relays – REJ601, REF601 and REM601 – maintains their cost effectiveness and minimal mounting footprint while adding functionality targeting ANSI markets, including UL Listed certification. The 605 series offers superior up-front value for applications needing three-phase overcurrent protection and even offers higher end options such as breaker control, auto-reclosing, communications, and Rogowski current sensors. Additionally, the 605 series excels in quick commissioning, retrofit-ability for overcurrent replacement applications, and space savings due to its small size.

“We are excited to offer our customers an optimized solution for utility and industrial installations,” said Richard Lindo, VP and General Manager for ABB Distribution Automation North America. “The 605 series’ small size, press-mount, pre-configuration ability, and simple settings make it the easiest set of relays to integrate into your protection system.”

This announcement was made at the ABB Automation & Power World conference and exhibition, ABB’s bi-annual customer event held this year in Houston.
