The circuit breaker is a kind of outdoor or indoor distribution equipment integrates switch technology, advanced network technology and microcomputer processing technology into itself. It is combined by three-phase integrated and embedded poles, current transformer, spring operation device and enclosure. The product is highly intellectualized and has the functions such as protection, monitoring and controlling. Besides, a variety of communication protocols is presented for selection. Its modularized design and easy operations for upgrade and maintenance make the convenience for clients. It is widely used in transformer substations, industrial and mining enterprises, rural power distribution automation grids and occasions where frequent operations are needed.

One-sided or double-sided disconnector can be selected, and there is a three-phase linkage in it. An obvious insulation distance can be seen on the disconnector when it is open. Moreover, there is an existence of linkage which is used to avoid misoperations between disconnector and circuit-breaker. The safety for using and the convenience of maintenance will be guaranteed.
