Each has a minimum melt melting current. Correspond to different temperature fuse, the minimum melting current is also different. Although affected by the current external environment Nantong Which fuse is good, but in practice may not be considered. Rated current ratio is generally defined minimum fusing current melt and melt the fuse for a minimum melting coefficient Changzhou Which is good, common melt melting coefficient greater than 1.25, that is rated for 10A of the melt in the current 12.5A below are not blown. To prevent leapfrog fuse, expanding the scope of the accident, on the lower level (ie supply dry, regional) between line fuses should be a good match. The selection should be made superior (supply mains) fuses melt lower than the rated current (power feeder) 1 to 2 large differential. Commonly used fuses have tube fuse R1 series, screw type fuse RLl series, packing enclosed fuse RT0 series and quick fuse RSO, RS3 series. Which is good, Xuzhou fuses, fuse, power is supplied by the Xi'an Huayi 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!
