Advantage Analysis

• Fast and Stable Opening and Closing Speeds

       Richge opening speed is approximately 20% higher than that of most domestic brands, and the closing speed control accuracy is higher (±0.1 m/s). It can complete opening within 0.5–1 cycle, significantly shortening the arc duration, improving arc extinction efficiency, and reducing the risk of contact ablation.      

• Moderate and Stable Operating Work

      The operating work is about 10% higher than the domestic average, ensuring stable contact closing pressure under various working conditions, reducing pre-breakdown and contact resistance, lowering operating temperature rise, and improving reliability.

• High Energy Transfer Efficiency

      Adopting an optimally designed spring operating mechanism and low-friction transmission system, the energy transfer efficiency reaches ≥92%, which is higher than the domestic average level (85–89%). This makes the actual output kinetic energy closer to the design value with better stability.

• Long Mechanical Life

      The mechanical life can reach 20,000 times, which is higher than that of mainstream domestic products (10,000–15,000 times). It has strong long-term operation reliability and low maintenance costs.

     In summary, Ruiqige vacuum circuit breakers excel in four key kinetic energy parameters: opening and closing speeds, operating work stability, energy transfer efficiency, and mechanical life. They are not only superior to most domestic brands but also comparable to international high-end brands. These advantages enable them to maintain stable opening and closing performance and long-life operation even under conditions of frequent operation, high short-circuit current, and harsh environments.
