Our high-performance vacuum circuit breaker represents the pinnacle of electrical protection technology, designed specifically for demanding power distribution applications. This advanced switching device utilizes vacuum interruption technology to deliver superior performance in substations, industrial power grids, and commercial electrical systems.
The breaker's innovative design incorporates a vacuum interrupter chamber that provides exceptional dielectric strength and rapid arc extinction capabilities. When current interruption occurs, the vacuum environment ensures quick arc quenching and reliable circuit breaking performance. This makes our vacuum circuit breaker particularly effective for handling fault currents and protecting electrical equipment from damage.
Key features include a robust mechanical structure with fixed and moving contacts manufactured from premium conductive materials. The arc control system is engineered to withstand the extreme thermal and electromagnetic stresses encountered during fault current interruption. With its compact design and minimal maintenance requirements, this circuit breaker offers a cost-effective solution for modern power systems.
The vacuum circuit breaker is available in multiple voltage ratings from 11kV to 33kV, with a standard rated current of 1250A. It comes with comprehensive protection functions including conventional circuit breaking, circuit-breaker failure protection, overcurrent protection, and overvoltage protection (OVP). The device meets international standards including ISO9001, CE, and CCC certifications.
Applications include power distribution networks, industrial plants, commercial buildings, and utility substations where reliable circuit protection is essential. The breaker's long electrical and mechanical life (rated E2 and M2 respectively) ensures years of dependable service with minimal downtime.
