What is the Icw rating for Compact NSX MCCBs?

We have no Icw (rated short-time withstand current) values for the NSX up to 630A. These devices have an utilization category A according IEC 60947-2 standards which means that they are not specifically intended for selectivity under short-circuit conditions with respect to other short-circuit protective devices in series on the load side. And as per IEC 60947-2, Icw not required for the utilization category A MCCBs and it only exists for utilization category B circuit breakers.
