Will the IPU SO-2M meter withstand a power of 11 kW?

Hello. Calculating the total power in this matter is at least silly for three reasons:

1. Your power is still limited by an introductory machine
2. The total power of your devices does not concern the power supply organization.
3. You will never turn on all these 11 kW appliances at the same time. Usually they are used alternately, unless we are talking about a powerful stove or boiler.

As for you, then you write that you have AB at 16A, how do you turn on 11 kW? Maximum 3.5 kilowatts. The meter is single-phase, so I suppose that the input is also single-phase. Nothing will happen to the meter, because 5A is its rated current, i.e. current at which the specified accuracy class of this meter is provided. on it must be indicated (at the bottom of the scoreboard) two numbers, for example 5-15A, which indicates that he easily withstands up to 15A, in practice, these meters continue to work under load up to 16A, for a short time and 25A. In any case, it needs to be changed for a long time, since its accuracy class does not meet the current requirements (accuracy class must be 2 and higher, and you have 2.5). Yes, not only the meter, but also your wiring will not withstand such a load.
