The ZW20 Intelligent Vacuum Circuit Breaker (Watchdog) is an outdoor high-voltage switchgear rated for 12kV, three-phase AC 50Hz. It is primarily used to open and close load currents, overload currents, and short-circuit currents in power systems. Suitable for protection and control in substations, industrial and mining enterprises, and urban/rural distribution networks, it is particularly well-suited for locations with frequent operations and automated distribution networks in urban grids. When paired with a controller, this product meets the requirements of distribution automation systems and reliably and effectively performs traditional recloser functions.
