- Description
The ABB 1SCA153622R1001 (OXB1600E3S2QB) is a 4-pole TruONE transfer switch rated 1600 A at AC-31B, stepping down to 1500 A at AC-32B and 1250 A at AC-33B for mixed and motor-starting duty. Its Level 2 DIP-switch controller keeps setup simple, supply feeds in from the bottom, and the 200-480 V AC switch carries a 65 kA / 0.1 s short-time withstand current.

Selection Notes
At 1600 A (AC-31B), stepping down to 1500 A (AC-32B) and 1250 A (AC-33B), this 4-pole, bottom-fed (QB) switch is rated for both distribution and motor-starting duty at the top of the TruONE current range. The Level 2 DIP-switch controller is the simplest control tier available at this frame size - choose the Level 3 or Level 4 siblings for on-panel display or touchscreen access. Four-pole switching is the right choice when the two sources have independently earthed neutrals.
