Technical characteristics of the strip type fuse switch disconnector

Fuse switch for the heat generated by their own, and therefore, according to the current exceeds a molten melt, so that the value of the circuit is disconnected after a period of time; current protection made using this principle. Fuse switch is widely used in high and low voltage power distribution and control systems and electronic devices, such as short-circuit and over-current protection, is the most common protective device in one. Consists of two parts of the base and the cover (load melt unit) fuse switch, fuse fuse is usually vertical rails, is a three-phase shunt closed structure, operation time being, covered by a transparent cover, you can directly observe the assembly Fuse - rated pieces of data, and indicate when the operation state, the switch can be equipped with NH000 or NH00 fuse two body sizes. Fuse switch with a compact, safe, reliable, convenient loading and unloading fuse body, a small touch operating force. Fuse switch has a simple structure, easy to use and inexpensive, price, etc., are widely used in low voltage systems.

Strip type fuse switch disconnector fuses typically use a full use of fuse-protected characteristic curve, in order to protect cables and wiring equipment and maintenance provide significant break points, in order to protect the personal safety of employees, and other intelligent systems can be expanded to open the device . Technical Features strip fuse switch disconnectors, mainly single break, double break, break with fuse switch disconnectors, which not only has a protective function, through other optional features of the system, to extend its functionality, so that it has greater flexibility, you can say this is not a simple switch in the form and, more importantly, it has a complete set of intelligent systems. Because there are many advantages of a fuse to protect irreplaceable, has been widely used in Europe, particularly in such applications in the protection of low voltage power cables and lines. Thus, a variety with fuse switch disconnectors successful application, due to its small size, safe, affordable technology and fuse switch combination of continuous development. Because there are many advantages of a fuse to protect irreplaceable, has been widely used in Europe, particularly in such applications in the protection of low voltage power cables and lines. Therefore, various types of fuse switch disconnectors successfully applied, because of technical and fuse switch combination of its small size evolving, safe, affordable, such as bar-type fuse switch disconnectors will play in wider areas such as power grids in terms of a greater role. With the deepening of rural power grid in recent years, the demand for such products will be greatly increased, and for the safety lamp, is also very necessary.
