Eaton CN15NN3 NEMA Size 4 Three Phase Motor Starter

The Eaton CN15NN3 is a Cutler-Hammer CN15NN3 Series B1 NEMA Size 4 three-phase motor starter designed for panel-mounted motor control in industrial settings. This unit, part of Eaton’s Cutler-Hammer lineup, identifies its place in the CN15NN3 family and its NEMA Size 4 frame, offering a compact, rugged solution for starting and stopping three-phase motors in control circuits. With its Series B1 designation, it follows Eaton’s standard architecture for three-phase motor starters, enabling straightforward integration into standard control panels and starter assemblies that rely on a conventional three-phase starter configuration. The CN15NN3 motor starter provides the essential control functionality to manage three-phase motor loads, and its NEMA Size 4 frame refers to its mounting footprint and enclosure compatibility within the CN-series ecosystem. The CN-series arrangement supports common wiring and mounting practices used by technicians working with Cutler-Hammer equipment, making it suitable for panel installations where reliable motor control is required within a compact enclosure.
