Electrical apparatus; automatic circuit breakers, for a voltage of 72.5kV or more

hs code 853529 covers the import and export of electrical apparatus, specifically automatic circuit breakers designed for high-voltage applications of 72.5kV or more. This industry plays a crucial role in the power transmission and distribution infrastructure, ensuring the safe and reliable operation of electrical grids worldwide. As the global demand for electricity continues to rise, the importance of this industry in supporting the broader economy cannot be overstated.

The production of high-voltage automatic circuit breakers involves a complex manufacturing process. Key steps include the fabrication of the circuit breaker's main components, such as the contact system, arc-extinguishing chamber, and operating mechanism. These components are then carefully assembled and tested to ensure compliance with rigorous safety and performance standards. Advanced engineering techniques, including the use of specialized materials and precision machining, are employed to create the robust and reliable circuit breakers required for high-voltage applications.

The production of hs code 853529 items requires a range of inputs, including 722410 (Electrical transformers, static converters (for example, rectifiers) and inductors), 853610 (Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, fuses, lightning arresters, voltage limiters, surge suppressors, plugs and other connectors, junction boxes), for a voltage exceeding 1,000 volts), and various specialized components such as insulating materials, circuit breaker mechanisms, and control systems. Additionally, the industry relies on skilled labor, advanced manufacturing equipment, and a robust supply chain to ensure the timely and efficient production of these critical electrical components.

The primary output of hs code 853529 is high-voltage automatic circuit breakers, which are essential for the safe and reliable operation of electrical power transmission and distribution systems. These circuit breakers are typically consumed by 853610 (Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, fuses, lightning arresters, voltage limiters, surge suppressors, plugs and other connectors, junction boxes), for a voltage exceeding 1,000 volts), as well as 853620 Boards, panels, consoles, desks, cabinets and other bases, equipped with two or more apparatus of heading 8535 or 8536, for electric control or the distribution of electricity, including those incorporating instruments or apparatus of chapter 90, and numerical control apparatus, other than switching apparatus of heading 8517, which are used in the construction and maintenance of high-voltage electrical infrastructure.
