A variety of terminal blocks are available to suit different wiring requirements of different users (modular structure)
The number of attachment devices has been greatly increased, and the accessories for all structures are completely common
Through the ZSI equipment, the subordinate circuit breaker can announce the delay and other information to the superior circuit breaker in time when it encounters a fault, so as to achieve the best choice, do not pollute the environment, and the data can be recycled;
It can be used as a main switch in certain occasions (such as replacing the structure, and then reducing the cost);
Due to the need for automatic control, it is required to be able to equip more accessories;
Able to communicate, connect with industrial computers for remote sensing, telemetry, and remote control; Prompt the cause of the fault and other values, the wiring is more sensitive, and the upper and lower circuit breakers can communicate with each other.
