ABB 1SCA153434R1001 OXB200E3X2QT 3P 200A 18kA Automatic Transfer Switch

The ABB 1SCA153434R1001 is a TruONE OXB200E3X2QT automatic transfer switch rated 200 A across 3 poles, withstanding 18 kA for 0.3 s. Its Level 2 DIP-switch controller handles basic dual-source transfer logic, and the QT terminal layout brings supply cabling in at the top with the load wired at the bottom.

Selection Notes

This 3-pole OXB200E3X2QT leaves the neutral unswitched across both sources, suited to installations where the neutral is already common; the 4-pole S version switches the neutral as well where that is required. At 200 A and 18 kA short-time withstand, it is intended for sub-distribution duty rather than a main incomer. A Level 2 DIP-switch controller handles basic transfer logic without a display, unlike the Level 3 and Level 4 variants in the same frame. QT termination brings supply cabling in at the top, the opposite of the QB layout.
