Abstract
An arrester is disclosed. In an embodiment an arrester includes at least one first and one second electrode, a ceramic body for electrical isolation of the electrodes, wherein the electrodes are spaced by a distance from one another in a direction of a transverse axis of the arrester, and wherein the distance between the electrodes varies along a longitudinal axis of the arrester.
