Electrical Distribution Equipment
Resolution:
Connect the appropriate voltage (ie. 120V to 240V for the -1021 suffix) to the two terminals on the shunt trip. Land the switch leg from the source contact on one terminal (either) and the neutral wire (L2 , X2 ) to the other terminal. The shunt trip has coil clearing contacts that open when the voltage is applied so either momentary or maintained contacts can be used to initiate voltage.
Shunt trip accessories in QO(B) are factory installed only and can not be added to an existing breaker.
The accessory terminals will accept (2) #14 - 12 Al/Cu.
