ZW20-12F series outdoor high-voltage AC boundary vacuum circuit breaker is rated voltage 12KV, three-phase AC 50Hz high-voltage outdoor switchgear, mainly used to open and close the load current, overload current, short-circuit current of rural network, urban network and small power system. The overall structure of the product is three-phase common box type, three-phase vacuum arc extinguishing chamber in a metal box, reliable variable voltage performance, high insulation strength.
The operating mechanism of this series of products is spring energy storage type, which is divided into electric and manual two kinds. The circuit breaker meets the requirements of GB1804, DL403, GB11022 and other standards, whether it is under normal conditions of use or under fault conditions (especially short circuit), as long as the number of pole parameters of the circuit breaker are within the range, it can ensure safe and reliable operation in the power grid of the corresponding voltage level.
