The excellent performance of the fuse circuit protection, overload protection performance in general. If it proves necessary to use the overload requires careful matching circuit overload current and fuse rated current. For example: 8A melt for circuit 10A fuse in Liaocheng Which is good, as the short-circuit protection doubles as overload protection with fuses Dongying Which is good, but not ideal at this time overload characteristics. Fuse by an insulating base (or support member), contacts, and other components melt, the melt is the main working portion of the fuse, melt equivalent series in the circuit of a special section of the wire, when the circuit is overloaded or short-circuited fuses, current is too large, the melt due to overheating and melting, thereby cutting off the circuit. Melt often made filament, grid-like or flake. The melt material having a relatively low melting point, stable characteristics, easy fusing characteristics. General use of pewter, silver plated copper, zinc, silver and other metals. In the process of melt blown off the circuit will produce an arc Texas fuses Which is good, in order to safely and effectively extinguish the arc, generally installed in the fuse will melt the casing, take measures to quickly extinguish the arc. Which fuse Dongying | Huayi Electric Power (certified) | fuses provided by Xian Huayi power plant.
