            Summary
            0.4 kV outdoor low voltage cable branch box is suitable for the urban residential area, industrial and mining enterprises, construction site, three-phase ac 380/220 v. 50 hz. rated current under 1600 a and in the power system, as a branch cable wiring and control and protection purposes.
            Function characteristic
            1. condensation prevention, resistant to dirty, can be used in all kinds of bad environment;
            2. flexible combination, can choose a bar fuse type load isolation switch or molded case circuit breaker protection;
            3.outdoor installation, compact structure, small volume;
            4.can choose unsaturated resin, glass fiber reinforced polyester (SMC) or stainless steel box body;
            5. body color is regular army green, gray, also can according to user requirements to choose the first.
            Model and meaning
            Technical data
            0.4kV low voltage cable branch box
            1.stainless steel or ordinary steel body (type B) cabinet put oneself in another's position Is made of more than 1.5 mm steel plate bending welded together. the intensity is high, multi-channel process of corrosion on the surface, floor or wall installation, use waterproof structure, protection level is IP44
            The structure design of natural ventilation.
            2. glass fiber reinforced polyester material box (type A) cabinet put oneself in another's position Plate assembly structure, die-casting molding, insulation, corrosion resistance, anti-aging, modelling is beautiful and easy. natural ventilation design, prevent condensation level is IP44
            Line
            3. mistress Using T2 high purity copper platoon, the surface tin plating, three-phase main circuit connected to the system and power transmission, lI arge flow, low temperature rise
            4. neutral busbar Using T2 high purity copper platoon, the surface tin plating, neutral point connected to the system and power transmission, large flow, low temperature rise.
            5. busbar protective grounding (bus)
            Using T2 high purity copper platoon, the surface tin plating. connect to the site, large flow, convenient connection
            6. insulator High quality composite insulation material more, support and a fixed bus, high mechanical strength, leakage resistance index higher.
            7. molded case circuit breake Installed in the outlet loop, with overload, short circuit and under-voltage protection function. Can according to user needs, choose a variety of types and technical parameters of molded case circuit breaker. Can be installed in vertical or The level of the installatior
            8. isolating switch fuse type load bar Unipolar or three pole load isolation switch with current-limiting fuse to maintain, can be connected, bearing and breaking the normal load current, and form a clear visible fracture, over loading and short circuit protection function.
            9 terminal blocks, Suitable for 25-300 was wire core, apply to the circular, the fan conductor, carrying capacity is big.
