Abstract
A fuse apparatus ( ) is provided for selectively interrupting a load current (I ) flowing between a pair of associated conductor leads. The fuse apparatus includes at least two spaced apart electrically conductive contact elements ( ) operatively connected with the associated conductor leads. A fuse element ( ) is connected to the contact elements ( ) using an electrically conductive connection material ( ) to allow the current (I ) to flow between the pair of associated conductor leads. The connection material ( ) is adapted to electrically disconnect the fuse element ( ) from the contact elements ( ) when the current (I ) exceeds a predetermined current intensity. The connection material ( ) has an intrinsic electrical transition resistance characteristic whereby the material develops a temperature in proportion to an intensity of the current. The connection material melts as the current increases to separate the fuse element from the contact elements.
