Does Compact NS/NSX Switch Disconnector (NA) have the Reflex Tripping.

Yes, Reflex Tripping is available in all Compact NS/NSX Switch Disconnectors.

The threshold of the Reflex Tripping auto-protection is about 20xIn and time delay is less than 10 ms, as shown in the attached tripping curves.

The Reflex Tripping is due to "Piston - which is purely mechanical” and not due to the trip unit.
 
Thus the Reflex Tripping being a mechanical controlled function is also available in the Compact NS/NSX Switch Disconnectors.
