Abstract:
A surge arrestor, comprising:a middle electrode; at least one outer electrode; an electrically conductive spring clip that is secured to the middle electrode and exerts a spring power on the at least one outer electrode, an electrical component part that is non-conductive at a trigger voltage of the surge arrestor, configured to generate heat given a flow of current, the electrical component part being arranged between the spring clip and the at least one outer electrode, a spacer element to which the spring clip is secured with a fusible mass, the spring clip being spaced away from the outer electrode, the spacer element having a tapering at a section lying between the outer electrode and the spring clip, the elements being so arranged that when the fusible mass becomes molten, the spring clip is pressed against the at least one outer electrode.
