Note: 32 communicable circuit breakers can be connected on one line at the same time. The maximum wiring distance is
1,200 meters, and the communication distance can be extended by installing intermediate relays.

Busbar temperature detection and protection
The busbar temperature protection function is realized by external temperature acquisition module or built-in
temperature sensor. The temperature acquisition module can monitor the temperature of 8 busbars at the same time,
and the built-in temperature sensor monitors the temperature of the conductive busbars in the circuit breaker body.
Through RS-485 communication mode, the intelligent controller can read the busbar temperature data of the
temperature acquisition module in real time, calculate and process the data according to the preset protection
parameters, and realize the functions of busbar overtemperature tripping and overtemperature alarm.
