Product introduction:
ZW32- 12 series outdoor AC high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are outdoor power distribution equipment with rated voltage of 12KV and three-phase AC of 50Hz. It is mainly used for interrupting load current, overload current and short circuit current in electronic systems. It is suitable for the protection and control of substations and distribution systems in industrial and mining enterprises and places where rural power grids operate frequently. It can also be used as a sectional switch of power grid, and distribution automation can be realized after adding a controller.
The above is the manufacturer information of some high-voltage vacuum circuit breakers. Perhaps this kind of products are rarely touched in our life, but when buying, we often choose this kind of products more carefully than other things. If you buy unqualified products, it is easy to have accidents in your daily life. Even if there is no accident, once it breaks down, it will have a great impact on your daily life and work. Therefore, when purchasing this kind of products, buyers must find trusted merchants, learn more about manufacturers' information and choose qualified products.
