Abstract (en)
[origin: EP3413320A2] An overvoltage protection device (100) includes a first electrode member (122), a piston-shaped second electrode member (124), and a varistor assembly (150). The varistor assembly includes: a plurality of varistor wafers (152, 154, 156) each formed of a varistor material; and at least one electrically conductive interconnect member (160, 162) 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. The assembly further comprises a bonding agent (164, 164') bonding at least two of the varistor wafers in the varistor assembly to one another.
