Fuse is an overcurrent protection device. Mainly from the melt and fuse melt plus filler pipe and other components.
In use, the fuse connected in series with the circuit to be protected, the protected circuit when the current exceeds a predetermined value, and after a certain time, the heat from the melt blown melt self-generated, so that the circuit is opened, thus protecting the effect. As melt metal conductor and breaking electrical circuits, connected in series with the circuit, overload or short circuit when the current through the melt, melt and fuse itself will generate heat, thus the power system, a variety of electrical equipment and appliances have played a a protective effect. An anti-delay characteristics, when the overload current hours, long operating time; Overload current large, fusing time is short. Thus, within a certain range of the overload current to the current returns to normal, the fuse will not blow, you can continue to use.
As a melt using a metal conductor in series in the circuit when the overload or short-circuit current through the melt,
Its self-heating and fuse, thus breaking an electrical circuit. Fuse simple structure, easy to use, widely used in power systems, various electrical equipment and household appliances as a protective device.
