ELECTRICAL COMPOSITE DEVICE

摘要

An electrical device capable of functioning as either a resettable device or a nonresettable device according to conditions. As such an electrical device, there is provided an electrical composite device comprising a polymer PTC device and, connected in series therewith, a temperature fuse member, wherein the temperature fuse member is disposed so as to fall under a thermal influence from the polymer PTC device, and wherein the melting point of the metal constituting the temperature fuse member is at least 5°C higher than that of the polymer constituting the polymer PTC device.
