CN15DN3AB - Eaton Contactor

CN15DN3AB - Eaton Contactor

The CN15DN3AB Eaton Freedom NEMA motor control contactor is a 27A device used in industrial and commercial motor control systems where reliable daily motor switching is required. In real-world applications, this is the type of component you’ll find inside control panels running equipment like HVAC systems, pumps, conveyors, compressors, and general industrial machinery.

In practice, this contactor is used in systems that are already built around NEMA motor control standards. It’s commonly selected for replacement work, panel maintenance, or new installations where Eaton Freedom components are already in place. Because it’s part of the NEMA Size 1 lineup, it fits cleanly into compatible motor control centers and panels without requiring changes to the existing layout.

It features a common control design, which helps keep wiring simple and familiar in standard motor control circuits. In the field, that usually means quicker replacement work and easier integration into existing Eaton Freedom systems. Its compact Size 1 frame also helps when panel space is limited or when matching existing equipment is required.

At its core, this contactor is designed for one job — switching motors reliably in systems that depend on predictable operation and straightforward control.
