Selection Notes
Rated AC-31B only at 1600 A, this 4-pole, top-fed (QT) switch is the distribution-duty option in the largest TruONE frame in this batch; the QB sibling adds AC-32B/AC-33B ratings for motor-load switching. The Level 3 LCD controller gives local status readout without touchscreen cost. Supply-on-top, load-on-bottom terminals suit boards fed from an overhead busway rather than from below.
