Electrical Composite Element
First Claim
1. An electric composite element comprising(a) a polymer PTC element comprising a polymer having a melting point, and(b) a temperature fuse member comprising a metal having a melting point, said temperature fuse member connected in series with the polymer PTC element,said electric composite element is characterized in that the temperature fuse member is placed such that it is under the thermal influence of the polymer PTC element, and the melting point of the metal is at least 5°
- C. higher than the melting point of the polymer.

Abstract
An electric device that functions either as a reverting (resettable) type element or a non-reverting (non-resettable) type element depending on the conditions. Such an element includes a polymer PTC element and a temperature fuse member connected in series thereto, the temperature fuse member placed such that it is under the thermal influence of the polymer PTC element. A melting point of a metal composing the temperature fuse member is at least 5° C. higher than a melting point of a polymer composing the polymer PTC element.
