Abstract: The present disclosure specifies a varistor comprising a ceramic body, which comprises a functional ceramic, and electrodes arranged inside the ceramic body. The electrodes include non-floating electrodes, which are electrically connected to external contacts of the varistor, respectively. The electrodes include at least three floating electrodes, which are electrically isolated with respect to the external contacts. At least two floating electrodes are arranged in the same layer, and each of the floating electrodes overlaps with at least two further electrodes. At least two floating electrodes overlap with one of the non-floating electrodes, respectively. A distance (D1) is defined along a longitudinal axis of the ceramic body between two of the electrodes overlapping with a first floating electrodes, and a distance (D2) is defined perpendicular to the longitudinal axis between the first floating electrode and one of the overlapping electrodes. The distance (D1) is at least twice the distance (D2).
