The JCZ5 High Voltage Vacuum Contactor is designed with an integrated insulated frame and high-quality vacuum interrupters, ensuring excellent electrical performance and long-term reliability. Its optimized structural design provides stable operation, simple secondary control, and a fully insulated external cover, enhancing both safety and appearance. To improve operational efficiency, our company has upgraded the transmission mechanism of the JCZ5 vacuum contactor, resulting in a compact structure, high synchronization accuracy, and minimal contact bounce. The product line includes three operating types—electromagnetic holding, mechanical holding, and permanent magnet holding—allowing users to select the ideal mechanism based on different application requirements. Among them, the mechanical holding vacuum contactor is our patented design. It delivers stable and wear-free operation, long service life, low switching current, and zero power consumption during holding, making it an energy-efficient and cost-effective solution for high-voltage control systems. The JCZ5 series is widely applied in high-voltage power distribution, motor control, and capacitor switching, providing users with a reliable and efficient high-voltage vacuum contactor solution.
