Abstract

An overvoltage protection device includes a first electrode member, a second electrode member, and a varistor assembly. The varistor assembly includes: a plurality of varistor wafers each formed of a varistor material; and at least one electrically conductive interconnect member connecting the varistor wafers in electrical parallel between the first and second electrode members. The varistor wafers are axially stacked between the first and second electrodes.
