Abstract
An electrical protection component with a short-circuiting device includes a surge arrester including at least two electrodes. The electrical protection component has at least one fusible element having a geometrical form including at least one cavity. A short-circuiting link is arranged at the surge arrester, wherein the short-circuiting link presses onto the fusible element. The short-circuiting link is spaced apart from the electrodes by means of the fusible element.
Claims24
An electrical protection component with a short-circuiting device, comprising:
- a surge arrester comprising a plurality of electrodes that are located at end sides of the surge arrester;
- a short-circuiting link arranged at the surge arrester;
- and
- a fusible element having a geometrical form comprising at least one cavity, wherein the fusible element comprises an insulating material, wherein the fusible element is located between one of the electrodes at the end sides and the short circuiting link;
- wherein the short-circuiting link presses onto the fusible element, and wherein the short-circuiting link is spaced apart from the one of the electrodes by the fusible element, wherein the fusible element has a geometrical form comprising a slotted tube or a hollow cuboid or a planar material that is folded.
