DEFINITION

Classification: 337/403

(under subclass 402) Subject matter wherein the mechanical contact control means is adapted to interrupt a controlled electrical circuit automatically upon the melting or otherwise destruction of the fusible element or elements. The separating means usually consists of spring or other energy storage structure held under compression or tension until release by the melting of the fuse, whereupon the contacts are forcibly opened.
