This product is used for real-time monitoring of key electrical factors in power lines, such as voltage, current, power, temperature, leakage, energy consumption, etc. It has functions such as remote control, early warning protection, short circuit protection, energy metering statistics, fault location, etc.

It consists of a switch body and a controller. The main function of the controller is to detect the working status of the power supply. When the detected power supply malfunctions, the controller will issue instructions, and the switch body will quickly switch to another power supply to ensure continuous power supply for the equipment.

It is suitable for distribution lines with AC 50Hz, rated voltage below 690V and rated current up to 4000A, which are used for infrequent connection, disconnection or Galvanic isolation. The product shell adopts a fully enclosed design of glass fiber reinforced unsaturated polyester resin, which has high dielectric properties, good flame retardancy, carbonization resistance, and impact resistance, good protective ability, and reliable operational safety.
