An output line has two branches, each of which is provided with a corresponding circuit breaker. The high voltage circuit breaker apparatus is housed in a metal covered housing which is divided into a plurality of areas which are provided with an insulating medium of higher grade than air at atmospheric pressure. Each of the circuit breakers is in direct electrical contact with a corresponding one of the bus bars and with the other circuit breaker. The circuit breakers are separated from each other by a partition in the housing and each bus bar is separated from the corresponding circuit breaker by a partition in the housing. The output line is electrically connected directly to a circuit breaker.
