    Abstract: A switching device (102, 104, 106) for electric power distribution, electrically connectable to an electrical conductor (114, 116, 118), the switching device comprising a breaker (126, 128, 130), the breaker being electrically connectable to the electrical conductor, and an at least partially electrically conductive housing (120, 122, 124) to which the breaker is mounted. The switching device provides a current path between the breaker and the electrical conductor. The housing houses at least one guiding member (150, 152) for operating the breaker. The housing houses a first part (131) of the current path between the breaker and the electrical conductor, the first part of the current path being electrically connected to the breaker, wherein the switching device comprises a switch (144) for electrically connecting the breaker to the electrical conductor, the switch comprising a switch element (146) movable to a first position in which the switch element is electrically connected to the first part of the current path and to the electrical conductor, movable to a second position in which the switch element is disconnected from the electrical conductor and electrically connected to the first part of the current path and to a grounded element (192), and movable to a third position in which the switch element is disconnected from the electrical conductor and from the grounded element. A switchgear for electric power distribution comprising at least one such switching device.

    Abstract: A load disconnecting circuit is disclosed with a housing that has a first housing section, which houses the drive, and has a second housing section, which houses a fixed contact element and a longitudinally extended moving contact element. The second housing section has a longitudinal extension adapted to the moving contact element. Field-control rings are placed on the second housing section while encircling it, of which the first are arranged in the vicinity of the fixed contact element and the second are arranged in the vicinity of the switch-off position of the moving contact element. Via a respective connection conductor, the first field-control ring is connected to the potential of the fixed contact element, and the second field-control ring is connected to the potential of the moving contact element when in its switch-off position.
