The vacuum circuit breaker is a crucial component in modern electrical power systems, designed to provide reliable interruption of current flow in high voltage applications. Utilizing vacuum as the arc-quenching medium, this device offers superior performance compared to conventional circuit breakers.

Our vacuum circuit breakers feature a robust construction with fixed and moving contacts made from high-conductivity materials, ensuring excellent erosion resistance and long service life. The vacuum interrupter technology provides rapid arc extinction and quick dielectric recovery, making these breakers ideal for critical power distribution applications.

These breakers are widely used in substations, industrial power grids, and commercial power distribution systems. Their compact design, high reliability, and low maintenance requirements make them a cost-effective solution for various electrical applications. The units come with multiple protection functions including overcurrent protection, circuit-breaker failure protection, and overvoltage protection.

With standardized production processes and strict quality control, our vacuum circuit breakers meet international standards including ISO9001, CE, and CCC certifications. We offer customization options to meet specific project requirements and provide OEM/ODM services for bulk orders.
