Since the 1980s, ABB has installed more than 700,000 SPACOM relays used for power system protection and reliable power system operation.

Accordingly, ABB has been actively developing new technology and expanding its service portfolio to replace select SPACOM relay types with REX610 relays. This is because of the aging of older generation relays.

REX610 is the first all-in-one protection relay to support all basic power distribution applications with only six variants. For that reason, making it easy to order, set up, use and service. This relay can also adapt during its entire lifetime to meet the shifting requirements for protection, communication, and network.

Maximizes Operational Uptime

Keen to help customers modernize their protection and control systems, ABB‘s new Relay Retrofit Program offers a streamlined transition from SPACOM relays to REX610 to ensure increased productivity and efficiency through further improved reliability of power supply.

“We understand that maximizing operational uptime, continuous power, and the safety of both their employees and equipment is of paramount importance to our customers. Opting for this program not only means adopting the latest technology for improved functionality, reliability and safety, but also extending the lifetime of a switchgear and offering the possibility to adapt the power protection system to meet new requirements,” says Paresh Mandpe, the Global Product Manager for Electrification Service.

In addition, Mandpe said the design of Relay Retrofit Program allows customers to schedule and execute their retrofit project in phases to ensure timely replacement. At the same time, to minimize downtime to production or power distribution processes to a bare minimum. In addition, installation is fast as the SPACOM relays and REX610 have the same cutout dimensions – saving customers both time and money.

In fact, the new program involves a fast and streamlined installation process that includes a configuration template, which ensures the REX610 relay configurations are matched to each SPACOM relay default configuration. Furthermore, the new mounting assemblies feature pre-wired terminals to minimize the need for re-wiring and thereby the need for updating existing wiring diagrams.

Fully Modular Hardware

The Retrofit Program for SPACOM to REX610 relays is the latest addition to ABB’s service offering. Particularly, it covers the entire replacement process, with ABB experts providing holistic expert advice, tools and accessories throughout the engineering, installation, testing aspects of the project.

REX610 relays offer equivalent functionality of SPACOM relays with a possibility to configure additional protection functions. As REX610 fully supports the IEC 61850 standard for communication and interoperability of substation automation devices, the program also provides an opportunity to upgrade the entire communication system at the same time. Hence, helping to better meet today’s protection and communication requirements.

In addition, REX610 has fully modular hardware and a broad selection of default functionality. Hence, it comes with optional add-on access to a web-based data-sharing and backup service, ABB Ability™ Backup Management for electrical systems – Data Care. All firmware updates will also be accessible. This provides secure online storage and easy sharing of technical information from the protection relays.
