Abstract
A switch-fuse module includes: a security device, a fuse; and a fuse canister having the fuse inside. The security device includes at least one slider linearly movable between open and closed positions; an earthing switch that is galvanically connected to the fuse, and is coupled to the slider such that the open position effects an open state of the earthing switch and the closed position effects an closed state of the earthing switch; a propulsion element configured to move the earthing switch from the open to the closed state when discharging; and a locking mechanism configured to block access to the fuse in a locked state. The slider is coupled to the locking mechanism such that the slider in the closed position while the locking mechanism is in the unlocked state, so that the fuse is only accessible if it is ensured that the fuse is earthed.
