ZW8-12 electronic type PT outdoor high voltage vacuum circuit breaker is used in the power system of three phases, AC50Hz, voltage 10~12KV, to break, make loading current, it can automatically absorb charging energy, adjustable surge limiting, over-current and quick melting protections. The breaker can be charged and switched for several times even if 10KV system is power off, to perform local remote control and cable control from long distance and automatic distribution. Also it can be used as non-power-source switch for incoming outgoing I ine inside or outside substation, to form RMU power supply, integrated power source protection and control and communications functions.
