OEM Carrier 2-Pole Contactor 30 Amp 120V Coil (HN52KC052) for Model 09DE084510

This OEM contactor is the factory-specified high-voltage relay for the Carrier 09DE084510 HVAC unit. The contactor serves as the primary switching device that closes the high-voltage circuit to the compressor and condenser fan motor each time the thermostat calls for cooling. When the contactor fails — whether due to burned or pitted contacts, a welded-shut set of poles, or a failed coil — the system will either refuse to start, run continuously without shutting off, or trip the breaker entirely. Replacing it with the correct OEM part restores factory-spec switching performance and protects downstream components from irregular voltage events.

• Specs: 2-pole | 30 Amp | 120V AC coil | 50/60 Hz rated | OEM Part # HN52KC052 | Factory Authorized Parts
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact contact gap, coil pull-in voltage, and thermal rating specifications. Generic contactors frequently use lower-grade silver alloy contacts that arc and pit faster, reducing service life and risking compressor damage from voltage irregularities.
• Install difficulty: 2/5 — Always disconnect power at the breaker and verify voltage is absent with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, camera or phone to photograph existing wiring layout before removal. Label wires before disconnecting.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier 09DE084510. Verify coil voltage (120V) and amperage (30A) on your unit's data plate or wiring diagram before ordering. Not sure if this is the right part?
