Product <\/b><\/strong>Overview<\/h2>\n

The CQB3LE-63 series residual current operated circuit breaker is thoughtfully designed by CHAC Electric to meet the customization needs of international clients in low – voltage electrical systems. As an experienced contract manufacturer with a strong export focus, we provide exceptional ODM\/OEM services. These leakage MCBs are ideal for AC 50Hz distribution systems with a rated voltage of 230\/400V and a rated current up to 63A. When a person gets an electric shock or the grid leakage current exceeds the specified value, the residual current operated circuit breaker can automatically cut off the power supply within a short time, ensuring personal safety and preventing accidents caused by leakage current. Equipped with overload and short – circuit protection functions, they can be used to protect lines from overload and short circuits. In normal conditions, they can also serve as devices for infrequent conversion of lines. Our CQB3LE-63 series is suitable for various venues such as industrial, commercial, high – rise, and residential buildings. Our CQB3LE-63 series stands out due to advanced technology and strict quality control. Using cutting – edge equipment and following strict quality standards, we guarantee reliable performance. We understand international clients’ unique needs and offer flexible customization from product design to packaging. Our efficient processes and quality systems ensure timely delivery of high – quality products, helping clients compete globally.<\/p>\n

    CQB3LE-63 series residual current operated circuit breakers are suitable for circuits with AC 50Hz, rated voltage up to 230\/400v, and rated current up to 63A. When a person is electrocuted or the leakage current of the power grid exceeds the specified value, the residual current operated circuit breaker can automatically cut off the power supply in a short time to ensure personal safety and prevent accidents caused by leakage current of the equipment. The residual current operated circuit breaker also has overload and short circuit protection functions, which can be used to protect the line from overload and short circuit, and can also be used for infrequent line conversion under normal circumstances.
