This product is a composite component cavity that adopts a flameproof structure. The busbar cavity and the inlet and outlet cavities adopt an increased safety structure. Using modules (building blocks) to combine each circuit, you can freely select and assemble it. There is also a warning sign that it is strictly prohibited to open the lid while the power is on.
, cast aluminum alloy shell aluminum alloy is a die-cast product with a smooth surface using an advanced high-temperature one-time die-casting molding process. The metal structure is fine and there are no bubbles or trachoma inside the shell. The product has good impact resistance and the explosion-proof performance of the product shell is significantly improved. The product has a permanent explosion-proof mark and trademark directly die-cast from the mold. The second level of explosion-proof box adopts plane explosion-proof and the second level adopts cylindrical explosion-proof. The flat flameproof surface adopts an exclusive explosion-proof and waterproof flameproof surface embedded sealing strip sealing structure. The cylindrical flameproof surface adopts a cylindrical embedded sealing strip sealing structure and has sufficient locking force.
In order to ensure that the aluminum alloy is resistant to strong corrosion, we have taken the following measures. We use surface shot blasting to clean the surface of the die-casting shell to better eliminate stress and enhance the adhesion of subsequent plastic spraying. , the industry took the lead in using electrophoresis technology to enhance anti-corrosion performance. , using domestic advanced high-voltage electrostatic spraying technology for surface spraying and advanced fully automatic drying line equipment, the plastic layer has uniform adhesion and strong adhesion. The anti-corrosion, anti-oxidation, and sunlight performance are significantly improved, which is much better than the traditional spraying process.
, Schneider can be installed inside:,, series high segment circuit breakers with overload, short circuit protection and other functions. It can also be equipped with leakage, auxiliary, separation, alarm and other modules. The above components can also be selected according to user requirements.
, All circuit breakers are operated on the box surface. The switch is connected to the external handle through a rotating shaft, and the shaft sleeve is a cylindrical flameproof surface. Made of high quality copper material. The explosion-proof surface has high precision and reliable explosion-proof performance.
, are equipped with indicator lights. And the indicator light adopts high brightness, long life, low power consumption and explosion-proof indicator light developed by our company using German technology.
Because our company's series of explosion-proof circuit breakers are modular combinations, different incoming and outgoing line cavities can be used according to the size of the user's incoming and outgoing cables. There is sufficient wiring space for the equipment when running with load and for a long time. It can fully dissipate heat when running under the working voltage without affecting the life and function. And it is very convenient for users to install and maintain.
The internal wire connections are all step-locking cylinder type connection structure with firm crimping, anti-vibration and anti-loosening. The multi-stranded conductors should be connected to the terminals after crimping the tubular ends to ensure the stability of electrical performance. The color of the wires is completely in accordance with the national standard. The inlet and outlet are equipped with pipe threads and cable clamping sealing devices. Both steel pipe and cable wiring are acceptable.
The direction of cable entry and exit can be made according to user requirements. The inlet and outlet are equipped with pipe threads and cable clamping sealing devices. Both steel pipe and cable wiring are acceptable.
The product color is light cyan. All exposed fasteners are stainless steel.
The installation method of the distribution box is generally hanging type. It can be made into vertical type if there are special requirements.
, Cable configuration method: input++∕output∕++.
