Abstract
This hybrid circuit breaker has at least two series-connected arcing chambers which are operated by a common drive or by separate drives and are filled with different arc extinguishing media. The arc extinguishing and insulating medium in the first arcing chamber surrounds the second arcing chamber in an insulating manner. The aim is to provide a hybrid circuit breaker which can be produced economically and which has high availability. This is achieved, inter alia, wherein means are provided which always ensure that the movement of the first arcing chamber leads the movement of the second arcing chamber during a disconnection process, and that the movement of the second arcing chamber always leads the movement of the first arcing chamber during a connection process.
