Home / Products / Vacuum circuit breaker / Outdoor Vacuum Circuit Breaker
This product is an outdoor distribution device rated at 24kV, three-phase AC 50Hz, mainly used to switch and close/open the load current, overload current, and short-circuit current within power systems, suitable for protection and control purposes in substations and industrial/mining distribution systems, and for frequently operated locations on rural grids.
Features:
The product is compact and lightweight, resistant to condensation, and maintenance-free, able to adapt to relatively harsh climatic conditions and polluted environments, providing stable and reliable long-term outdoor operation and greatly reducing maintenance workload and cost.
Applications:
Widely used on overhead lines and distribution zones of urban and rural grids, undertaking load control, overload protection, and short-circuit fault clearance, particularly suitable for outdoor distribution applications with relatively harsh climate conditions requiring frequent operation.
