Cabinet configuration instructions
The switchgear is composed of two parts (see Fig. 2). The cabinet is divided into four separate compatments, and the prolection level of the
enclosure is P4X, each cubicle and circuit breaker When the door is open, the degree of prolection is P2x, Overhead access with overhead lines,
cable eniry and other functions and programs, through the arrangemen, after the combination of a varety of programs to become the distribution
device. The switchgear can be instaed, debugged and maintained from the front so that it can be rear-to-back double-aigned and wal-mounted,
increasing the safety and flexibility of switchgear and reducing fioor space.
