Eaton Cutler-Hammer C320kg5 Aux Contact Block

The Eaton Cutler-Hammer C320kg5 Auxiliary Contact Block adds two normally closed (2NC) auxiliary contacts to compatible Eaton Cutler-Hammer contactors, with a 10 A rating. The NC contacts remain closed in the de-energized state and open when the associated coil is energized, providing signaling and interlock capability for control circuits. As a mounted accessory, it expands a contactor’s control-side contacts without altering main power contacts, making it suitable for stop/start interlock logic, feedback signaling, and simple safety interlocks in industrial panels. The part number C320kg5 identifies this unit as a two-contact auxiliary block designed for use with Eaton Cutler-Hammer equipment, delivering reliable auxiliary signaling paths in a compact form.
