Electrical apparatus; automatic circuit breakers, for a voltage exceeding 1000 volts but less than 72.5kV

HS v2017 Code: 853521

About electrical apparatus; automatic circuit breakers, for a voltage exceeding 1000 volts but less than 72.5kv

hs code 853521 covers a critical component of electrical infrastructure - automatic circuit breakers for high-voltage applications. These devices play a vital role in protecting power grids, industrial facilities, and other high-voltage electrical systems from overloads and short circuits, ensuring the safe and reliable distribution of electricity. As a key part of the 853500 Electrical apparatus for switching or protecting electrical circuits industry, this code is essential for maintaining the integrity and stability of power networks worldwide.

Production process

Automatic circuit breakers within the 853521 classification are typically manufactured using a combination of precision engineering and advanced materials. The production process often involves the careful assembly of components such as contacts, arc-extinguishing chambers, and operating mechanisms. Specialized techniques like high-voltage insulation, arc-quenching design, and precise contact alignment are critical to ensure the breakers can reliably interrupt high-current faults without failure.

Production inputs

The production of 853521 circuit breakers requires a range of inputs, including high-grade electrical contacts, insulating materials, and specialized mechanical components. Manufacturers may also rely on advanced manufacturing equipment, such as CNC machines and automated assembly lines, to ensure consistent quality and efficiency. Additionally, the industry consumes a variety of raw materials, including metals, polymers, and ceramics, which are transformed into the necessary breaker components.

Production outputs

The primary output of the 853521 industry is, of course, automatic circuit breakers designed for high-voltage applications. These breakers are essential components in a wide range of electrical systems, including power transmission and distribution networks, industrial facilities, and large-scale commercial buildings. The output of this industry is often consumed by other 853500 Electrical apparatus for switching or protecting electrical circuits manufacturers, as well as by 853610 Electrical apparatus for switching or protecting electrical circuits, for a voltage not exceeding 1000 volts producers.
