- Description
The ABB 1SCA153577R1001 (OXB1000E3S2QB) is a 1000 A, 4-pole TruONE automatic transfer switch with an open-style, delayed I-O-II transition and a Level 2 DIP-switch controller built into the switch body. Rated 200-480 V AC with +/-20% tolerance and Icw 65 kA for 0.1 s, it feeds line power in on the bottom and sends load out on top.

Selection Notes
DIP-switch setup on the Level 2 controller is enough when the transfer parameters rarely change and no event log or remote monitoring is needed. Choose the bottom-supply, top-load (QB) terminal layout when upstream cabling runs below the switch; its QT sibling reverses that for top-fed installations. Move up to the Level 3 LCD or Level 4 touchscreen controller when the application needs on-screen status or more detailed transfer-timing adjustment.
