DEFINITION

Classification: 337/240

(under subclass 239) Subject matter including a flexible fusible element, as one component of the fuse link, in combination with a wire or other strain member. The strain member is designed to take the full force of the spring tensioning means as long as the fuse is conducting thereby protecting the fuse from any tensile stress. Usually, as soon as the fuse ruptures and becomes nonconducting, the strain wire becomes heated and in turn is ruptured thereby allowing the ends of the fusible element to be separated.
