This article describes an experimental study of high breaking capacity fuses with aluminum fuse element with and without eutectic point at minimum rated breaking current preceded by experiments at maximum rated breaking current. It is shown that, in this construction with aluminum fusible element, the fuse has no problem to break the maximum rated breaking current, it has real difficulties with minimum rated breaking current. The experiments were made on a homogeneous series 6-20 A, with focus on the 36 kV, 25 kA, 16 A fuse, which suffered multiple construction changes and tests with and without eutectic point. It was found an acceptable constructive solution, that passed the tests but the obtained value for the minimum rated breaking current is not a commercial attractive value.
