Eaton C320KG3 Auxiliary Contact

The Eaton C320KG3 Auxiliary Contact is a critical field-installable component designed for integration with 15A through 75A definite purpose contactors. This side-mounted block features a 1NO-1NC circuit configuration, allowing for simultaneous status signaling and electrical interlocking within HVACR control circuits. Engineered with standard pressure plate terminals, the C320KG3 ensures secure, vibration-resistant wire terminations suitable for rigorous industrial environments. It serves as a direct functional equivalent to P69580 auxiliary contacts, providing seamless compatibility for contractors maintaining Freedom Series or C25 contactor assemblies. By utilizing high-conductivity silver cadmium oxide contacts, this unit minimizes resistance and extends the service life of auxiliary signaling paths. Whether you are adding a secondary pump interlock or a remote status indicator, this Eaton side-mount aux contact delivers the mechanical reliability required for high-cycle motor control applications.

Key Benefits for HVACR Applications

• Enhanced Circuit Logic: Provides both normally open and normally closed contacts for versatile control sequences.
• Universal Compatibility: Fits the footprint of 15A to 75A Eaton C25 contactors and identical OEM series.
• Efficient Installation: Side-mounting design snaps into place without requiring specialized tools or disassembly of the main contactor.
• Robust Terminals: Standard pressure plates accommodate multiple wire gauges, ensuring high-torque connection stability.
• Direct Cross-Reference: Fully interchangeable with part number P69580 for simplified inventory management.

Common Technical Questions

How do I install the C320KG3 on an existing contactor?
This auxiliary block snaps onto the side of the definite purpose contactor frame. Simply align the mechanical actuator with the contactor's moving crossbar and slide until locked. Verify the 1NO-1NC contact state with a multimeter before energizing the control circuit.

Can this be used for 3-pole and 4-pole Eaton contactors?
Yes, the Eaton C320KG3 is compatible with the side mounting slots found on most 15A-75A C25 series frames, regardless of the number of main power poles.

What is the difference between C320KG3 and P69580?
There is no functional or physical difference; C320KG3 is identical to P69580. They are the same technical specification used interchangeably in various manufacturer catalogs.
