Abstract: An arc chamber for a DC circuit breaker includes an entry side adapted to receive an electric arc, which was generated outside of the arc chamber and which propagates in a forward direction, a plurality of stacked splitter plates, and at least one inhibitor barrier. The at least one inhibitor barrier is arranged on the entry side to inhibit a reverse propagation of the electric arc out of the arc chamber in a reverse direction. DC circuit breaker comprising an arc chamber. Use of an arc chamber with a circuit breaker in a DC electrical system.

Abstract: A switching apparatus includes first and second electric terminals, and first and second electric branches comprising one or more switching devices. The second electric branch is electrically connected in parallel with said first electric branch between said first and second electric terminals. The switching apparatus comprises a current blocking circuit adapted to block a current along said second branch. The current blocking circuit includes a first switching device of solid-state type and a first electronic circuit electrically connected in parallel to said first switching device of solid-state type. The switching apparatus further comprises a current limiting circuit adapted to limit a current flowing along said second electric branch. Said current limiting circuit is electrically connected in series with said current blocking circuit and it includes a second switching device of solid-state type and a second electronic circuit electrically connected in parallel to said second switching device of solid-state type.

Abstract: A switching apparatus for an electric grid includes first and second electric terminals, each having first and second electric branches having a plurality of switching devices. The first electric branch includes a first switching device switchable between open and closed states, which is driven by a current flowing along said first switching device and without receiving an external control signal or an external power supply, said first switching device switching from said closed state to said open state, when the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or when the changing rate of the current flowing along said switching apparatus exceeds a corresponding predefined threshold value or upon a combination of these two conditions. A second switching device is connected in series with the first switching device and is switchable between closed and open states upon receiving a corresponding input control signal.
