Eaton Cutler-Hammer C320KGS3 Auxiliary Contact

The Eaton Cutler-Hammer C320KGS3 is a heavy-duty side-mounted auxiliary contact block designed for seamless integration with Freedom Series starters and contactors. This specific configuration provides one normally open (1NO) and one normally closed (1NC) contact set, essential for complex interlocking circuits, status signaling, and remote monitoring in industrial motor control centers. Engineered for durability in high-cycle applications, the C320KGS3 is compatible with NEMA Size 00 through 2 starters and IEC Frames A through K, making it a versatile component for field modifications and control circuit expansions. The side-mount design allows for rapid installation without increasing the depth of the starter, maintaining a compact footprint within the electrical enclosure. By providing reliable electrical feedback, these auxiliary contacts ensure precise sequencing and fail-safe operation for HVACR and manufacturing equipment.

• Universal Compatibility: Fits a broad range of Cutler-Hammer Freedom Series NEMA and IEC contactors.
• Snap-On Installation: Facilitates quick field mounting on the side of the base unit to minimize downtime.
• Bifurcated Contact Design: Enhances electrical reliability even in low-voltage logic-level circuits.
• Space Efficiency: Side-mount configuration preserves DIN rail or panel space by keeping the profile low.
• Enhanced Logic Control: The 1NO/1NC arrangement allows for simultaneous signaling of "run" and "stop" states.

Is the C320KGS3 compatible with larger NEMA Size 3 starters?

No, the C320KGS3 is specifically rated for NEMA Sizes 00-2 and IEC Sizes A-K. For larger frame sizes, a different auxiliary contact series is required to match the physical mounting bracket.

Can I mount multiple C320KGS3 blocks on a single contactor?

Yes, Freedom Series contactors typically allow for multiple auxiliary blocks to be stacked or mounted on both sides, depending on the specific frame size and enclosure clearance.

Does this auxiliary contact work for low-energy PLC inputs?

The silver cadmium oxide contacts are designed for standard industrial control voltages; however, for very low-current PLC applications, ensure the minimum switching threshold meets your controller's requirements.
