Type PMG-B, 245 kV, up to 63 kA Power Circuit Breaker

       The PMG-B breaker evolved from the quality ABB type PMG breakers, merging components, expertise and outstanding performance history into a breaker that provides enhanced performance with exceptional long-term reliability. 
       The 245PMG-B breaker principally consists of three cast aluminum single-piece tanks, each containing an interrupter unit, mounted on a powdercoated steel support structure. Two bushings with removable current transformers mount atop each tank. A powdercoated steel control cabinet is attached to the frame, while the moving contacts are gang driven by an externally mounted spring-hydraulic operating mechanism.
