Eaton XT IEC Series contactors are used in motor control circuits, motor starters, HVAC systems, lighting control panels, power distribution, and other industrial control applications. They are designed to handle high electrical currents and provide reliable switching and protection for electrical loads. These units are integrated with spring cage terminals to secure and connect electrical conductors, eliminating the need for tools or manual tightening of screws. They offer non-reverse capability that is generally used in applications where motor rotation in a single direction is required.
