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.
