ZW32-12F-High-Voltage-Intelligent-Vacuum-Circuit-Breaker
Product Overview ZW32F-12F outdoor high-voltage AC intelligent vacuum circuit breaker is a user boundary switch independently developed by our company. It is mainly composed of ZW32-12 type outdoor vacuum circuit breaker body, FDR fault detection controller and external voltage transformer. The three parts are electrically connected through aviation sockets and outdoor sealed control cables. With fault detection function, protection control function and communication function, it can reliably judge and detect milliampere-level zero-sequence current inside and outside the boundary, and phase-to-phase short-circuit fault current, and realize automatic removal of single-phase ground fault and phase-to-phase short-circuit fault....
