How can we perform earth leakage protection for ratings above 3200 A (used with MAsterpact NW ACB) ?

For Masterpact ACB of ratings higher than 3200 A, it is more commen sense to protect against the ground fault not the earth leakage protection as it will be of neglected value with respect to the nominal current

so for the ratings higher than 3200 A, we tend to use micro logic 6.0 (for ground fault protection) rather than earth leakage protection
