Fuse holder for distribution panel - adaptable to ambient conditions, having number of heat sinks formed from U=profile sheets bolted in stacks

摘要

A fuse holder for an electrical distribution panel allowing it to be equipped to the maximum filling factor. The fuses used are adaptable to different environmental conditions and the nominal current is reduced. The fuse holder is made with a number of heat sinks (7) to convey the heat developed by the current through the fuse. The heat sinks are independent removable components fitted to the fuse holder. They are made from flat plates bent to form a U-shaped cross-section. They are stacked one inside the other and bolted together. The upstanding walls are coated with a layer which promotes heat dissipation.
