Selection Notes

The OXB1600E3X4QT carries the same 1600 A, 65 kA rating as the rest of this frame, positioning it for main-incomer duty. Keeping the neutral unswitched (the X build) suits installations with a single bonded neutral; the S (4-pole) variant switches the neutral as well where that's required. A Level 4 touchscreen controller gives full access to transfer settings and logged events, the most capable interface in this range - the Level 2 and Level 3 variants trade that down for a simpler DIP or LCD interface. The QT termination routes supply cabling in at the top, the opposite of the QB version.
