Eaton CN15DN3AB 3 Pole NEMA Open 3 Phase Contactor

The Eaton CN15DN3AB is a size-1, three-pole NEMA open contactor designed to switch three-phase loads with a 120V coil. This open-style 3P device is commonly used to control motors, fans, and pumps in industrial control panels, providing centralized, coordinated switching of all three supply lines when the coil is energized. The open construction exposes internal terminals for straightforward wiring and maintenance inside compact enclosures, while the three poles ensure simultaneous interruption of each phase for reliable motor control. With a 120V coil, this CN15DN3AB is tailored for control circuits that use standard line voltages, simplifying integration with common control wiring schemes and relays. Typical applications include industrial machinery, conveyor systems, and HVAC-related equipment where a compact, NEMA-rated contactor is required to reliably switch 3-phase loads.
