<p>A fuse assembly is provided, comprising a main fuse element; an indicator fuse element, arranged electrically in parallel with the main fuse element; and an indicator assembly. The indicator assembly comprises an indicator movable between a first position and a second position, a biasing means biasing the indicator to the second position, and the indicator being retained in the first position by the indicator fuse element against the action of the biasing means. The biasing means is may be a helical spring or an arrangement of opposing leaf spring elements. Melting of the indicator fuse element releases the indicator for movement from the first position to the second position, the biasing element acting to provide a biasing force against the indicator fuse element substantially along the line of the retaining force exerted by the indicator fuse element. The general application of leaf spring elements to provide the biasing force for fuse assembly indicator assemblies is also disclosed. <IMAGE></p> |
