ledscale electrical components are fuses capable of multiple operations, known in Japan as permanent fuses. Immediately after interrupting an overload or short-circuit current, the fusible element automatically restores to its original state. The housing is made of austenitic stainless steel, with a beryllium oxide ceramic core embedded in the center. The space between the stainless steel and the ceramic core is filled with glass to seal and secure the core. The fine pores of the ceramic core are filled with metallic sodium as the fusible element, and the void behind the piston is charged with argon gas to compress the metallic sodium. Under normal operating conditions, current enters from lead terminal A and passes through the metallic sodium within the fine pores of the ceramic core.
