A switching device for electric power distribution, includes a breaker that is electrically connectable to a conductor, and an electrically conductive housing to which the breaker is mounted. The device provides a current path between the breaker and the conductor. The housing houses at least one guiding member for operating the breaker and a first part of the current path, the first part being electrically connected to the breaker. The device also includes a switch for electrically connecting the breaker to the conductor, the switch having a switch element movable to a first position where the switch element is connected to the first part and the conductor, movable to a second position where the switch element is disconnected from the conductor and connected to the first part and a grounded element, and movable to a third position where the switch element is disconnected from the conductor and the grounded element. |
