Rated for 10,000 operations, ABB's 38 kV R-MAG outdoor vacuum circuit breaker provides more than five times the IEEE requirement for endurance capabilities.

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–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 that is suitable for a wide range of climatic and environmental conditions. Embedded in a solid insulating material with high dielectric strength, the vacuum interrupters are insulated from external effects of mechanical shock, dust and humidity.
