ABB Expands Magnetically Actuated Outdoor Breaker Technology to 38 kV



Rated for 10,000 operations, the 38 kV R-MAG breaker provides more than five times the IEEE requirement for endurance capabilities.

Raleigh, North Carolina, - ABB, the leading power and automation technology company, announces the release of the 38 kV R-MAG outdoor vacuum circuit breaker.

First introduced in 2002 for 15 kV and 27 kV applications, the R-MAG breaker utilizes a magnetic actuator design that has only one moving part, offering an improvement over the traditional spring charging mechanism. Rated for 10,000 operations, the 38 kV R-MAG breaker provides more than five times the IEEE requirement for endurance capabilities. Additionally, the magnetic actuator requires no regular maintenance during the life of the breaker, thus reducing costly maintenance intervals, while increasing reliability and safety.

The 38 kV R-MAG breaker takes advantage of embedded pole technology, providing a compact and modular design, suitable for a wide range of climatic and environmental conditions. Embedded in a solid insulating material of high dielectric strength, the vacuum interrupters are insulated from external effects of mechanical shock, dust, and humidity.

The R-MAG breaker is field proven, with thousands of units in service globally. ABB magnetic actuator technology delivers the state-of-the-art in distribution class breakers, while providing reduced maintenance costs and increased reliability our customers.

ABB (www.abb.com) is a leader in power and automation technologies that enable utility and industry customers to improve performance while lowering environmental impact. The ABB Group of companies operates in around 100 countries and employs about 117,000 people. The company's North American operations, headquartered in Cary, North Carolina, employ about 12,000 people in 20 manufacturing and other major facilities.
