The three-phase rail mounted energy meter adopts the design of measuring three-phase four wire or three-phase three wire active energy, so it is often used in enterprises and institutions that implement single rate electricity prices, commercial residential users, and electrical equipment with limited space and environment. The safety and reliability of an electric energy meter enable it to achieve optimal performance during use. At the same time, its small size and lightweight quality save a lot of time and cost during transportation and handling. In terms of decorative effect, the design incorporates simple and fashionable elements, making its appearance simple, elegant, and beautiful. The simple structure also makes installation and disassembly operations flexible and convenient.

The working temperature of the three-phase rail mounted energy meter ranges from minus 20 degrees Celsius to plus 70 degrees Celsius, which is its maximum temperature. It can be seen that its environmental adaptability is excellent. The display screen of the meter adopts a special design, which allows the screen to display the number 6 clearly and accurately. Its power comes from a three-phase power source. In the event of a power outage or failure of any one or two lines in the energy meter circuit, its measurement accuracy is not affected because it has the function of storing data and values in advance.
