R-MAG - outdoor magnetically actuated circuit breaker

The industry-proven magnetic circuit breaker

ABB recognizes the industry’s focus on safety and reliability and helps meet these goals with the R-MAG® circuit breaker for medium-voltage primary substations. Based on magnetic actuation, the R-MAG has fewer moving parts and is mechanically simpler than breakers with traditional spring mechanisms. The durable R-MAG design and low maintenance requirements have been consistently tested over the past decade in over 10,000 installations.
