OEM Carrier 2-Pole Contactor 30 Amp 120V Coil — HN52KC052 for Model 09DE146100

This OEM Carrier contactor (part number HN52KC052) is the factory-specified high-voltage relay for the Carrier 09DE146100 commercial HVAC unit. The contactor acts as the primary switching device that completes the high-voltage circuit to the compressor and condenser fan motor each time the thermostat calls for cooling. When the contactor fails, the control board sends the 120V signal to the coil — but nothing happens. Common failure symptoms include the system not turning on at all, the compressor failing to energize, audible clicking with no motor start, or pitted/burned contact points visible on the relay face.

• Specs: 2-Pole | 30 Amp (32A rated) | 110–120 VAC Coil | 50/60 Hz | Screw terminal connection | Single phase
• OEM vs Generic: This is a genuine Factory Authorized Parts (FAP) OEM contactor built to Carrier's exact coil pull-in voltage, contact gap, and arc-suppression spec. Generic contactors may use thinner contact material, leading to premature pitting, coil burnout, and repeated callbacks.
• Install difficulty: 3/5 — Always shut off power at the disconnect and verify zero voltage with a multimeter before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and camera/phone to photograph wiring before removal. Label every wire before disconnecting from the old contactor.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier 09DE146100 commercial HVAC equipment using a 2-pole, 30A, 120V coil contactor configuration. Always verify coil voltage and amperage rating on your unit's data plate before ordering.
