Eaton Cutler-Hammer C306DN3 3-Phase Contactor

Eaton Cutler-Hammer C306DN3 is a 3-phase contactor used to remotely switch power to three-phase motors and other heavy loads in industrial control panels. The model belongs to the Cutler-Hammer family and is identified by the C306DN3 part number, indicating a standard 3-pole device designed for control via a low-voltage coil. In motor control circuits, it serves as the main switching element of a starter, often used together with overload relays and protective enclosures to start and stop three-phase equipment. These devices simplify control wiring by handling three live conductors in a single action and are compatible with common control schemes, including PLC-driven and timer-based sequences. For exact coil voltage options, current ratings, contact arrangements (such as normally open or normally closed auxiliary contacts), mounting dimensions, and enclosure compatibility, consult the official Eaton C306DN3 datasheet or product specifications.
