The three-phase three wire rail type electricity meter has a relatively small volume, making it suitable for use in small and medium-sized enterprises, commercial and residential users who implement single rate electricity pricing, as well as in small space three-phase electrical equipment and other places. The product has good safety and reliability, small size, light weight, and beautiful and simple appearance. This design makes it very convenient and fast for transportation, installation, and disassembly operations, effectively saving a certain amount of manpower, material resources, and energy waste. In order to achieve high accuracy, precise measuring devices are installed in the internal structure, ensuring that the measured and displayed data have a certain degree of accuracy and precision.

The three-phase three wire rail type electricity meter equipped with a LCD digital display screen can clearly display the decimal point as a number, which has improved the accuracy and precision to a new level. The positive and negative active power of the electricity can be included in the measurement results. If there is a reverse measurement situation, the reverse indicator light will light up to indicate. The phase failure LED alarm prompt will provide an alarm prompt in case of special circumstances. When the three-phase power supply is used, any one wire of the three-phase three wire energy meter or any two wires of the three-phase four wire energy meter will be disconnected, and the measurement accuracy will not be affected.
