33kV High Voltage Vacuum Circuit Breaker for Power Distribution Systems

The 33kV High Voltage Vacuum Circuit Breaker represents the pinnacle of electrical protection technology for medium voltage power systems. This advanced switching device utilizes vacuum interrupters to provide superior arc-quenching capabilities, ensuring reliable operation and extended service life.

Engineered for demanding applications in power distribution networks, industrial plants, and substations, our vacuum circuit breaker features erosion-resistant contacts made from premium conductive materials. The vacuum chamber provides exceptional dielectric recovery strength, enabling rapid current interruption during fault conditions.

Key advantages include minimal maintenance requirements, compact design, and environmentally friendly operation (no SF6 gas). The breaker's robust construction withstands the high temperatures and energy associated with electrical arcs, while its rapid operation effectively protects downstream equipment from damage caused by short circuits and overloads.

With multiple protection functions including overcurrent protection, circuit-breaker failure protection, and overvoltage protection, this device offers comprehensive system security. The fixed installation design and three-pole configuration make it ideal for standard power distribution applications.

Available in various voltage ratings including 11kV, 22kV, and 33kV configurations, our vacuum Circuit Breakers meet international standards and carry CE, CCC, and ISO9001 certifications. Custom specifications can be accommodated to meet specific project requirements.
