Manufacturing Process of Components for Molded Case Circuit Breakers

The production of copper busbars begins with the selection of high-purity electrolytic copper. This material is chosen for its excellent electrical conductivity and mechanical properties. The copper busbars undergo surface treatments such as silver plating and nickel plating to enhance corrosion resistance and maintain stable contact resistance over time.

Step 2: Cutting and Shaping

Once the surface treatments are complete, the copper busbars are fed into automated cutting machines. These machines precisely cut the busbars according to the specified dimensions and shapes required by the design of the MCCBs. Accuracy in this step is crucial to ensure consistency and adherence to product specifications.

Step 3: Welding and Assembly

After cutting, the busbars are transferred to the production workshop for welding and assembly processes. Welding involves using high-temperature arcs to join the copper busbars with other metal components, ensuring secure electrical connections. Assembly includes riveting processes, where pressure and heat are applied to firmly connect the busbars with brackets or terminals, ensuring durability against vibrations and thermal variations during operation.

Step 4: Quality Control and Packaging

Throughout each stage of production, stringent quality control measures are implemented to verify that every busbar meets design requirements and industry standards. Advanced testing equipment and skilled technicians conduct thorough inspections to uphold quality assurance. Once validated, the busbars are carefully packaged to protect them during transportation and storage before being shipped to customers.
