The Eaton C320KG3 auxiliary contact block adds one normally open (N.O.) and one normally closed (N.C.) contact to compatible Cutler-Hammer contactors, providing a signaling path without carrying the main load. Designed for mounting on Eaton Cutler-Hammer control gear, it delivers feedback signals for control circuits, interlock logic, and status indications in industrial automation or motor-control applications. Model C320KG3 specifies this 1NO/1NC auxiliary block for use with compatible Eaton equipment to extend the control circuit's monitoring and signaling capability.
