Eaton Cutler-Hammer D15CR31 Three-Phase Contactor

The Eaton Cutler-Hammer D15CR31 Three-Phase Contactor is a dedicated device for energizing and interrupting three‑phase motor circuits, operated by a 120‑volt coil. This 120 V coil configuration means the control circuit energizes the contactor to close its main contacts and supply three‑phase power to connected equipment when commanded, enabling safe on/off control within industrial automation. Manufactured under the Cutler-Hammer line of Eaton, the D15CR31 identifies its coil and contact arrangement within standard control panels and motor control centers. The unit is designed for integration into panel assemblies where reliable switching of three‑phase loads is required, providing compact and robust operation for applications that use a 120‑volt control voltage.
