A high-current electric arc inside an electrical switchgear can be a source of danger to electrical equipment and technical personnel. The article shows that the use of hybrid connectors as an arc eliminator significantly shortens the time of electric arc burning, and as a result reduces the electric arc energy. As a result, an effective device was obtained to protect low-voltage networks against the effects of short-circuit or arc fault, such as sudden increase in temperature, gas pressure, high-intensity sound wave, equipment destruction, material erosion of power rails, ejection hot debris and molten metal particles in all directions. Inside the closed switchgear, the proposed arc eliminator solution will significantly reduce the build-up of pressure and temperature.
