NCX-10 / 200A non-breaking load type drop-out fuse

One, NCX fuse Overview: 1.1 NCX industrial fuse has to provide safe, reliable overcurrent protection for long-term history, NCX design will be possible due to system overload or fault condition caused by damage to the equipment to provide over-current protection. 1.2 NCX fuse for the power distribution system in addition to using it as a fuse load switch for outdoor use. Loadbreak by an independent load breaking arc and arc chute provided to limit the free role. Load breaking with routine operations hooked pole to pull the fuse properly. Loadbreak feature extends the life of the fuse. Separate loadbreak principle can achieve line worker with a common operating lever easily and safely cut off the load current. In addition, the flexibility of NCX fuse with the application, excellent features, easy installation, trouble-free operation and long life. Two, NCX fuse Model Description: three, NCX fuse Applications: 3.1 100A fusible element carrier will accommodate 6A ~ 100A rated current of the fuse. 200A planted melting pieces will hold the rated current of 100A ~ 200A fuse. For certain occasions, the appropriate fuse size and form of selection is to be bearing plant with continuous load current, with the type of protective equipment and other overcurrent protection devices required changes. In the form of protective equipment, including circuit breakers, reclosers and power cables and lines. 3.2 NCX fuse a variety of fault current breaking. Extended cap flexibility achieved through the use of a pressure relief cap or fuse. 100A is designed to release pressure cap under 13780kPa pressure exhaust, 200A under pressure release cap designed to 8957kPa pressure exhaust. Pressure relief cap makes NCX more effectively ionized gas ejected from the fuse tube and greatly improved its breaking capacity. Fuse cap extension request using a single jet configuration, the fuse extensions allow the fusible element in a lower position, thus reducing the pressure on a lot of the tube, which causes the fusion tube with a higher breaking capacity. Four, NCX type fuses according to the standard: NCX fuse and the design and testing to meet the following standards: NEMASG-2-1986 ANSI C37.41.1994, ANSI C37.42-1989 GB 15166.3-1994, DL / T 640-. 1997 NCX-12 / 100-12.5 NCX-12 / 100-12.5 NCX-12 / 200-12.5 NCX-12 / 200-12.5 five, NCX fuse institutions and its advantages NCX 5.1 melt tube fuse carrier agency melt melting tube for moisture. 5.2 NCX series fuse base by the embedded base of the mechanical structure and insulator components. Installation of mechanical metal rod with a special bond together, can withstand electric power generated when the short-circuit breaking current. 5.3 Advantages fuse tube with moisture does not absorb moisture, deformation, breaking capacity, anti-UV, long life and other advantages; has excellent electrical properties, dielectric strength and excellent mechanical rigidity, self-cleaning ability; the whole body of the neutral Well, easy to install, safe and reliable.
