The ABB AF750-30-11-70 is a 3-pole, non-reversing across-the-line contactor rated for 900 amp continuous current. The coil accepts 100-250 V AC or DC, and the built-in auxiliary stack gives you one normally-open and one normally-closed contact for feedback or interlocking. That 900 A frame size puts it squarely in heavy motor, large transformer, or main feeder switching duty — think 500+ hp induction motors at 480 V or primary bus coupling in a 2000 A panel.
The 100-250 V AC/DC coil is a universal pickup that works across control voltages common in both North American (120 V, 208 V, 240 V) and European (110 V, 230 V) panels, which simplifies stocking for multi-site builds.
The non-reversing type means this contactor switches power in one direction only — it is not mechanically interlocked for forward/reverse duty. If your application needs reversing, you would pair two of these with an external mechanical interlock, or step up to ABB's dedicated reversing contactor assembly.
