The excellent performance of the fuse circuit protection, overload protection performance in general. If it proves necessary to use high-voltage fuse overload in Nanning, requires careful matching circuit overload current and fuse rated current. For example: 8A melt for the fuse circuit 10A, also serves as overload protection for short-circuit protection, but this time overload characteristic is not satisfactory. Fuses and circuit breakers are able to achieve the same point short circuit protection, the principle is the use of electric current flowing through the fuse conductor conductor causes fever, reaching the melting point of the conductor conductor melted so disconnected circuit protection and electrical lines will not be burned. It is an accumulation of heat, so it can overload protection. Once burned to be replaced melt melt. High-voltage fuse fuse _ _ Dongguan Huayi electricity provided by the Xi'an Huayi power plant.
