Selection Notes

Because this 1250 A / 4P unit is rated AC-31B only, reserve the AC-32B/AC-33B-rated QB sibling for boards that switch motor loads directly, and use this top-fed (QT) version for standard distribution feeders instead. The Level 3 LCD controller gives local visibility of source and transition status. Switching phase and neutral together (4P) is the reason to pick this frame over the 3-pole equivalent whenever the two sources carry independently earthed neutrals.
