How to define the part number of NSX for Generator protection?

Please see the chart below and attached PDF. In the PDF you will find the information required on page A62

Micrologic G trip units are used for the protection of systems supplied by generators or comprising long cable lengths. They can be mounted on all Compact NSX100/160/250 circuit breakers.
With extensive setting possibilities, Micrologic 5 offers the same functions from 100 to 630 A. A thermal-magnetic trip unit is also available for the NSX100 to 250 (see page A-16). Circuit breakers equipped with Micrologic G trip units protect systems supplied by generators (lower short-circuit currents than with transformers) and distribution
systems with long cable lengths (fault currents limited by the impedance of the cable).
