I am shunt closing (XF option) an NW breaker on terminals A1, A2, A3. Which terminals do I use? Should the actuating voltage be maintained or momentary?

This is a communicating closing coil. A3 needs to be connected to the control power source. A1 is the switched hot connection, and A2 is the common. It can be activated with either a momentary or maintained voltage.
