Are the 5-7.5 A and 5-10 A counters interchangeable?
Hello, is it possible to replace the counter 5-7.5 A counter 5-10 A?
Good afternoon. The first digit is the base current, and the second is the maximum current. The maximum current is such a current at which the accuracy class of the electric meter is preserved and what current it can safely pass through itself.
Yes you can. If only the maximum current (10A) was not lower than before and not lower than the rating of the input circuit breaker (so as not to overload), but in general such questions should be asked to the company that will install and take this meter into operation, they may have some then more requirements.
