Abstract: A fuse device comprising a housing, at least two connection lugs, a connecting element between the connection lugs, and an actuator. The actuator moves the connecting element from a closed position, in which it connects the connection lugs, to an open position, in which it is disconnected from at least one of the connection tabs. A particularly well-conducting connection between the connection lugs and the connecting element, which can nevertheless be easily disconnected by the actuator, is achieved by the connecting element being interference-fitted between the connection lugs.
