Type PMI, 362 kV, up to 63 kA Power Circuit Breaker

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

The 362PMI breaker principally consists of three cast aluminum single-piece tanks, each containing an interrupter unit, mounted on a common 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 a spring-hydraulic operating mechanism mounted to each tank drives the moving contacts.
