    Tips: What is the mean of 5A in the energy meter 5(100)A?

    The 5 out of the brackets is called the basic current, or the demarcated current. It is determined by the start-up current of the energy meter. It is the minimum current enabling the energy meter to rotate and measure continuously.

    In normal conditions, the start-up current of the intelligent energy meter is 0.4% of the demarcated current. In other words, as to the energy meter with the demarcated current of 5A, as long as the current in the circuit reaches 0.02A, it will be charged.

    There is a ratio between the demarcated current and maximum rated current. For instance, 5(100)A has a relationship of 20 times. Such a ratio is called the "loading width". Generally, it can be 2 times, 4 times, 6 times, 8 times and even dozens of times. A bigger loading width requires a stronger technical level. In the meanwhile, the price of the energy meter will be higher naturally.

    Therefore, the figure out of the brackets has not too much relationship with the user's practical operation. The measurement of the energy meter will not be affected if it is higher or lower than the figure.

    Powerful kWh energy meter
    The three-phase electric kWh energy meter was exactly as advertised and listed, much appreciated! Our electrician had no experience with this model, but was able to install easily and so far, the unit is performing as expected.
