The Eaton C320SNP11 is a professional-grade side mounted auxiliary contact designed specifically for integration with 15A through 75A definite purpose contactors. As a veteran technician knows, maintaining reliable pilot circuit signaling is critical in HVACR applications, and this 1NO-1NC (One Normally Open, One Normally Closed) snap switch auxiliary contact delivers precise state feedback for starters and contactors in the Eaton Freedom Series and C25 families. Built with a robust metal mounting plate, this component provides the mechanical stability required for high-cycle industrial environments.

Engineered for seamless field installation, the C320SNP11 features standard quick connect terminals, allowing for fast wiring without the need for specialized lugging tools. This 1NO-1NC contact block is rated for 600V AC and up to 10A, making it a versatile choice for interlocking, status indication, or safety circuit integration. Whether you are servicing a Cutler-Hammer C25 contactor or upgrading an A25 starter, this Snap Switch design ensures positive contact engagement and long-term electrical integrity in demanding motor control circuits.

• Universal Compatibility: Specifically designed for 15-75A Eaton C25 Definite Purpose Contactors and Freedom Series starters.
• High-Reliability Switching: Features a snap switch mechanism that ensures crisp, decisive contact transitions to prevent arcing.
• Simple Integration: Equipped with 1/4-inch quick connect terminals for rapid job-site wiring and reduced downtime.
• Compact Side Mount: The side mounted auxiliary contact design preserves space on the mounting rail while providing essential multi-circuit control.
• Industrial Durability: Constructed with an open-frame design and a rugged metal mounting plate to withstand vibration in HVACR cabinets.

Can I use the C320SNP11 on a 90A contactor?
No, this specific snap switch auxiliary contact is engineered exclusively for use with 15A to 75A definite purpose contactors. For larger frame sizes, please refer to the C320KGS series or catalog specifications for appropriate compatibility.

What is the difference between a snap switch and a standard auxiliary?
A snap switch auxiliary contact utilizes a spring-loaded mechanism to snap the contacts open or closed regardless of the speed of the contactor's armature, ensuring reliable performance even in lower voltage pilot circuits.

Does this include one or two contacts?
The C320SNP11 is a dual-circuit block containing one Normally Open (NO) and one Normally Closed (NC) contact in a single side-mount housing.
