OVERVOLTAGE PROTECTION DEVICES INCLUDING WAFER OF VARISTOR MATERIAL .

摘要

An overvoltage protection device includes first and second electrically conductive electrode members, a varistor member formed of a varistor material and electrically connected with each of the first and second electrode members, and an electrically conductive, meltable member. The meltable member is responsive to heat in the device to melt and form a current flow path between the first and second electrode members through the meltable member.
