DEFINITION

Classification: 337/290

(under subclass 142) Subject matter including significant details of fuse link or fuse element structure or material of construction. The subject matter to be found here relates to the structure, including a fusible element, which serves to complete a conductive path from an input terminal of a fuse to the output terminal and which structure does not form a subcombination of a more comprehensive combination classifiable elsewhere in the class or in another art class.
