Use as a molten metal conductors in series circuit, overload or short circuit when an electric current fuse (Fig. 2) through the melt, due to its own heat and fuse, thus breaking an electrical circuit. Fuse simple structure, easy to use high-voltage fuse manufacturer Xi'an, widely used in power systems, a variety of electrical equipment and household appliances as a protection device. Select the main fuse protection features based on the size of the load and select the type of short-circuit current of the fuse. For small capacity motor and lighting branch fuses, fuse is often used as overload and short circuit protection, Xi'an high-voltage fuse Which is better, so I hope melt melting appropriate coefficient smaller. Usually used pewter melts RQA series fuses. For larger capacity motors and lighting trunk, you should consider focusing on short-circuit protection and breaking capacity. Typically used with a high breaking capacity fuses RM10 and RL1 series; when the short-circuit current is large, should have a limiting effect using RT0 and RTl2 series fuse manufacturer Xi'an high-voltage fuse, fuse, Huayi Electric Power provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Huayi power and you hand into the brilliant, for a better future!
