ZW8-12/C (ZW8-12-C) intelligent outdoor high-voltage vacuum circuit breaker (hereinafter referred to as intelligent circuit breaker) is used in AC 50Hz, voltage 10-12 kV local phase power systems, as a means of breaking and closing load currents. It has overload and short circuit protection functions, quick break protection functions, definite time delay protection functions, automatic reclosing functions, and can also be equipped with lightning arresters or isolation switches (i.e. circuit breaker and isolation switch combination, hereinafter referred to as "combined intelligent circuit breaker") according to user needs. This intelligent circuit breaker comes with its own power supply, can be remotely operated nearby, and is equipped with CT and PT interfaces to meet telemetry requirements.
