The KYN28 - 12 distribution and control box is designed for 3.6 ~ 12KV three - phase AC 50Hz power grids. It is mainly used for the acceptance and distribution of electrical energy, as well as circuit control, monitoring, and protection. It can be applied in single busbar, single busbar section, or double busbar systems. The handcart - type circuit breaker makes maintenance easy. This device is widely used in power substations, industrial and mining enterprises, hotels, communities, municipal construction, and the petrochemical sector for control, protection, and power distribution monitoring.
