Discrimination between NSX100 and iID

attached catalog pages explaining the method to select the appropriate circuit breaker and RCCB for an installation,in addition to coordination tables between NSX100 as upstream and iID as downstream.

You will find that there will be a partial discrimination in this combination up to 5KA only.

For higher short circuit values.The proposed solution could be the use of iC60H 63A rating (instead of NSX100 63A )as upstream,in this case the discrimination will be Total up to 15KA (for 380V Ph/Ph network).

But if the prospective short-circuit current at the installation is higher,so you will be obliged to use the vigirex and toroid for earth leakage protection.
