The permanent magnet outdoor VCB (high-voltage switching device) is designed for use in 7.2-40.5kV, three-phase AC 50Hz power grids. Utilizing a permanent magnet operating mechanism, it forms an intelligent circuit breaker when combined with a control terminal and PT (potential transformer). It is widely applicable as a feeder terminal in substations, in power distribution lines for industrial and mining enterprises, and in urban and rural power transmission and distribution systems for protection and control. It is particularly suitable for locations with frequent operations and for automated distribution networks in urban and rural areas.
