Overview
The Cutler-Hammer CE15DN3 /A1 is a Size D industrial contactor designed for motor control and circuit switching applications in commercial and industrial automation. This 3-pole unit operates from a 110-120V AC coil (50/60 Hz) and is rated for 18A switching capacity at 600V maximum operating voltage. The CE15DN3 combines proven IEC design with durable screw-terminal construction, making it suitable for integration into motor starters, control panels, and automation assemblies.
Key Features
- 18A UL AC3 Rating — handles medium-duty motor and load switching applications reliably
- 110-120V AC Coil — standard control voltage for North American industrial panels
- 3-Pole Configuration — switches all three phases simultaneously for balanced motor control
- 600V Maximum Operating Voltage — rated for high-voltage AC circuit environments
- Screw Terminal Connections — secure field wiring without ferrules or specialized tools
- Metal Base Mounting — stable installation in control enclosures and on DIN rail
