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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
