Abstract:
A protective device for safeguarding an electrical device against overcurrent, having the following features:an electrically conducting element (5) that fuses when the overcurrent is reached, a first (4) and a second operating voltage potential surface (3), which are connected in each case to an operating voltage supply lead (6, 7), the first operating voltage potential surface (4) is split into two, the two parts being connected by the electrically conducting element (5), and bounding walls that form a hollow body, the electrically conducting element (5) being situated inside, and the second operating voltage potential surface (3) being situated outside the hollow body, characterized in that the hollow body comprises the following features:an opening (8) that is at least so large that, in the event of tripping, metal vapor exits substantially through this opening (8), the opening points in a direction in space that differs from the direction in space in which the second operating voltage potential surface (3) is situated.
