Eaton Cutler-Hammer C320KGS31 Auxiliary Contact
Optimize your motor control circuits with the Eaton Cutler-Hammer C320KGS31, a heavy-duty 1NO auxiliary contact block engineered for the Freedom Series lineup. Designed for field installation on NEMA Size 3 and IEC Sizes L through N contactors and starters, this base auxiliary contact provides critical signal feedback for interlocking, status indication, and logic-level integration. It features a high-performance SPST-NO contact configuration with premium silver cadmium alloy contacts, ensuring superior conductivity and resistance to arc erosion in demanding industrial environments. Rated for 10A at 600VAC, the C320KGS31 utilizes a snap-on design for rapid, tool-free mounting, reducing labor time during panel builds or field upgrades. Whether you are replacing a factory-installed unit or expanding control capabilities, this motor starter accessory delivers the reliability required for high-cycle HVACR and motor control applications.
Key Benefits
- Precise Compatibility: Engineered specifically for Eaton Freedom Series NEMA Size 3 and IEC Size L-N frames.
- Durable Construction: High-grade silver cadmium alloy contacts resist welding and ensure reliable 600V auxiliary circuit operation.
- Streamlined Installation: Snap-on mounting simplifies the addition of contact points without complex wiring or specialized tools.
- Versatile Logic Integration: Bifurcated design makes this unit suitable for both standard 10A power control and low-energy logic-level circuits.
Common Questions
Can the C320KGS31 be used on both the left and right sides of the starter?
Yes, this base-mounted contact can be added to either side of compatible NEMA Size 3 starters; however, catalog number C320KGS31 is specifically the 1NO configuration commonly found in position 1.
What is the maximum current rating for this auxiliary block?
The unit is NEMA A600 rated, supporting up to 10A continuous thermal current at 600VAC, making it robust enough for most signaling and interlocking needs.
Will this work with IEC-rated Freedom contactors?
Exactly. It is fully compatible with IEC Sizes L, M, and N, providing a seamless crossover between NEMA and IEC motor control standards.
