Are the Masterpact NW breakers ``kiss-free`` when the shunt trip is energized?

The Masterpact NW and NT frame breakers are ``kiss-free`` when the shunt trip is energized. This means that the main contacts will not close even for an instant if a close attempt is made.
The continuously energized shunt trip blocks the ``Close`` button, preventing any mechanism action at all.
