VS1 (ZN63A) Vacuum Circuit Breaker

    Indoor High-Voltage Vacuum Circuit Breaker – In Production The Indoor High-Voltage Vacuum Circuit Breaker is an advanced circuit interruption device that uses high vacuum as both the arc‑extinguishing and insulating medium. Its core component is the vacuum interrupter, in which the moving and fixed contacts separate within a vacuum—generating an arc that is quickly extinguished by the vacuum medium, enabling reliable circuit closing and breaking. Key advantages of this technology include strong arc‑quenching performance, long service life, maintenance‑free operation, environmental friendliness (no oil, no SF₆), and suitability for frequent switching operations. This vacuum circuit breaker is designed for seamless integration into High‑Voltage Switchgearassemblies and can be coordinated with downstream Low‑Voltage Distribution Cabinet systems to ensure overall network protection. It supports connectivity with Transformer Automation Equipment for real‑time monitoring and control, w…
