Compact NSX MCCB peak current limiting curve

The green line is linked to 60947-2 standard table 2 representing the asymmetrical prospective peak current according to prospective short circuit current without limiting effect.

This line represents what would be the peak current seen downstream the breaker for a prospective short circuit current (abscissa) if the breaker would not be a limiter (Utilization category A).

This line is defined in IEC60947-2 standard table 2.

This information is only useful to see the effects of a current limiting breaker on the following points:
