Abstract: The invention relates to a load disconnecting circuit 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.

Abstract: Safety arrangement for a switchgear assembly, having a cylindrical insulating container, which consists of insulating material and is open at a first end, and into which a fuse cartridge or fuse can be inserted, the first end of said fuse cartridge or fuse being electrically conductively connected to a first contact arrangement and the second end being electrically conductively connected to a second contact arrangement. The fuse cartridge is fixedly connected at its first end to a closure apparatus for the insulating container, which closure apparatus has a sealing body (41) and a sealing head (43) connected to the sealing body (41). A spring arrangement (82, 83) is provided between the sealing body (41) and the sealing head (43).
