The invention relates to a medium voltage circuit breaker in highpressure subsea environment, with a vacuum circuit breaker in a pressure tight housing, according to the preamble of claim 1. In order to create a three phase switchgear for high environmental pressure, like in subsea, which is efficiently protected against this hight high environmental pressure, by fulfilling additionally high switching performance, the invention is, that for an electrical three-phase arrangement, one vacuum circuit breaker per phase is in arranged in a separate pole housing each, and the resulting three pole housings are mounted to a common base compartment, in which all the three drives for the three vacuum circuit breaker are arranged in. |
