Abstract
An overload and fault protector for a distribution transformer or the like is disclosed. A series-connected high range current-limiting fuse and a low range expulsion type fuse is provided with a transformer lead disconnect or ejection mechanism to insure a rapid, positive disconnect of the transformer or other power distribution circuit components. The ejection mechanism supports the transformer lead and completes the circuit to the fuse link assemblies. Upon separation of the fuse link, the ejection mechanism operates to quickly disconnect the transformer lead minimizing voltage stress on the fuse assembly and providing visible indication of a blown fuse.
