RS Breakers & Controls stocks a deep inventory of new, reconditioned, and obsolete fixed mounted air circuit breakers from all major manufacturers. As Canada’s leading supplier of air breakers, we carry units permanently bolted into switchgear compartments. Our technical team is available 24/7. All previously used units are tested to ANSI and CSA standards with a detailed test report and full 2-year warranty.
Fixed mounted air circuit breakers are permanently installed with bus connections bolted directly to the terminals. They offer lower cost and simpler mechanical design than draw-out configurations, commonly found in smaller switchgear assemblies.
As part of our comprehensive air breakers inventory, RS Breakers & Controls maintains deep stock of fixed mounted air circuit breakers across all major switchgear platforms, ensuring fast access to the equipment you need.
Our professional reconditioning services for air breakers include contact replacement, arc chute rebuilding, mechanism overhaul, and comprehensive testing to ANSI and CSA standards.
