Type PMR, 242 kV, up to 40 kA Power Circuit Breaker

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

The 242PMR 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.
