DEFINITION

Classification: 337/251

(under subclass 228) Subject matter wherein the cartridge or tube structure includes significantly recited metallic cap, ferrule or other conducting means normally attached to the tube and serving to complete an electrical circuit from one line terminal to another through the fuse element.

(1) Note. For other contact or terminal structures used in devices of this class, see the subclasses listed under subclass 26.

SEE OR SEARCH THIS CLASS, SUBCLASS:

248, for similar subject matter where the primary function of the ferrule or cap is to act as a seal.

413, for thermally responsive fuse devices with significant contact structure or composition of material.
