Selection Notes

The OXB250E3S3QT carries the 250 A rating within the same S-coded, 4-pole frame as its lower-current siblings, switching the neutral along with the three phases for installations where that is required. Its Level 3 LCD controller sits between the base Level 2 DIP and the touchscreen Level 4, giving an on-site display for transfer events without the full interface. QT termination routes supply cabling in at the top of the enclosure rather than the bottom, the reverse of the QB layout.
