Cutler-Hammer CN15DN3 Contactor

The Cutler-Hammer CN15DN3 Contactor is a 3-pole, three normally open (3NO) control device whose coil is energized at 120 V AC to control three independent contacts. Designed to switch three-phase motor circuits, the CN15DN3 consolidates control into a single coil that closes all three main contacts when energized, enabling reliable on/off control of connected equipment. With a 27 A current rating and a maximum motor power of 10 HP, this contactor is suitable for moderate-load applications in industrial control panels, automation gear, conveyors, pumps, and fans where compact, coil-driven switching is required. The 3-pole configuration supports synchronized switching across all three phases, contributing to smoother motor control and simplified wiring in panel layouts. This unit is intended for use in systems where a 120 V AC control voltage is used to actuate a contactor that handles higher power loads through its normally open main contacts.
