ABSTRACT:
Miniature plug-in fuses which include a first active pair of generally parallel blade contact elements which are connected by a first fuse link and a second spare pair of generally parallel blade contact elements which are oriented oppositely of the first pair of blade elements and are electrically insulated therefrom so that when the first fuse link is interrupted due to an overload in an electrical circuit, the plug-in fuse is reversed so that the second pair of blade contact elements and second fuse link provide a spare fuse of the same amperage rating.
