- Description
ABB's 1SCA153581R1001 (OXB1000E3S4QT) mirrors the Level 4 touchscreen-controlled, 1000 A, 4-pole TruONE switch with top-in, bottom-out line terminals instead of bottom-in, top-out. It is rated 200-480 V AC with +/-20% tolerance, withstands 65 kA for 0.1 s, and uses the same open-style, delayed I-O-II transfer logic found across the TruONE range.

Selection Notes
With line power entering from the top and load leaving from the bottom, this QT unit suits switchgear with overhead cable routing, the reverse of its QB sibling. It carries the same Level 4 touchscreen controller as the rest of the top-tier TruONE line, giving full graphical setup and status over the DIP-switch or LCD alternatives. Use it only where that configuration depth is actually needed, since the Level 2 and 3 controllers cost less for basic transfer duty.
