A surge protector includes a first surge suppression assembly comprising a first conductive layer comprising an arm, an extension distal to the arm and having toothed edges, and a substantially C-shaped member projecting out of the extension and having toothed edges, and a substantially circular member with toothed edges formed at an open end of the extension; a second conductive layer comprising an arm including a terminal, an extension being distal the arm, a first substantially C-shaped member having toothed edges, and a second substantially C-shaped member at an open end of the extension wherein the first substantially C-shaped member, the substantially C-shaped member, the second substantially C-shaped member, and the substantially circular member are arranged concentrically; and an overvoltage protection assembly interconnecting the arm and the terminal. The overvoltage protection assembly is electrically connected to the first surge suppression assembly.
