Type PM, 38-72.5 kV, up to 40 kA Power Circuit Breaker

       With a large installed base and proven track record, the PM breaker offers unequalled performance and reliability.

        The 72PM breaker principally consists of three cast aluminum single-piece tanks, each containing an interrupter unit, mounted on a galvanized steel support structure. Two bushings with removable current transformers mount atop each tank. A steel control cabinet is attached to the frame, while the moving contacts are gang driven by a spring or spring-hydraulic operating mechanism within the cabinet.
