Overview
The Eaton Cutler-Hammer C320KGS1 is a Freedom series auxiliary contact accessory for NEMA-rated starters and contactors. This 1NO (normally open) contact block features a side-mount installation and snap-on design for quick integration into existing contactor assemblies. The bifurcated contact design with silver-cadmium alloy provides stable switching performance in low-energy logic circuits, making it ideal for PLC input signaling, control panel interlocking, and status monitoring applications.
