R-MAG - Outdoor Magnetically Actuated Circuit Breaker

ABB R-MAG - Outdoor Magnetically Actuated Circuit Breaker

R-MAG industry-proven magnetic circuit breaker 

The R-MAG® circuit breaker for medium voltage primary substations enables ABB to meet and exceed the industry standard for safety and reliability. Magnetically actuated, the R-MAG circuit breaker has fewer moving parts and requires less maintenance than breakers with traditional spring mechanisms. The durable R-MAG circuit breaker design and low maintenance requirement have been field-tested over 20 years  in more than 50,000 installations, in 10+ different countries.
