DEFINITION

Classification: 337/181

(under subclass 180) Subject matter including terminals or contacts adapted to complete and maintain closed an electrical circuit directly through contact with a fusible means. The fusible means acts as a holding means for the terminals or contacts until ruptured or destroyed by an excess current. When the fuse is ruptured the contacts are allowed to separate under the influence of spring or other biasing means thereby opening the circuit.

190, for a combination of a fuse with a housing casing or support where the support includes fusible element tensioning means, which means may be released when the fusible element is ruptured.
