Abstract
A medium voltage circuit breaker in a high pressure subsea environment includes: a vacuum circuit breaker; and a drive in a pressure tight housing. For an electrical three-phase arrangement, one vacuum circuit breaker per phase is arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which three drives for the three vacuum circuit breakers are arranged. The three pole housings and the common base compartment are attached such that they commonly form a pressure tight compartment.
