ABSTRACT:
An insulating support for fusible elements in ribbon form having points of drastically reduced cross-sectional area which reduces the dimensional stability of the fusible elements to such an extent that they are not capable of supporting themselves. The support consists of a strip of electric insulating material arranged in spaced relation from, and parallel to, the fusible element. The strip has a plurality of arms projecting transversely from the former. Each of said plurality of arms supports the fusible element at a region situated between points of drastically reduced cross-sectional area thereof.
