OEM Carrier 2-Pole Contactor 30 Amp 120V Coil — Model 09DE064510 (HN52KC052)

This is the genuine OEM Carrier contactor (part #HN52KC052) factory-specified for the Carrier 09DE064510. The contactor is a high-voltage switching relay that controls electrical flow to the compressor and condenser fan motor. When the thermostat calls for cooling, the 120V coil energizes, closing the contacts and allowing line voltage to reach the load components. When it fails, you'll typically experience symptoms like the system failing to start, audible chattering or humming at the unit, or — in a welded-contact failure — the system running continuously even when the thermostat is satisfied.

• Specs: 2-Pole | 30 Amp (FLA) | 120V Coil | 50/60 Hz | Factory OEM tolerance — drop-in replacement for HN52KC052
• OEM vs Generic: OEM contactors use factory-matched silver-alloy contact tips rated to exact amperage thresholds. Generic contactors often use lower-grade contacts that pit and weld sooner, risking compressor lockout or continuous-run damage to the refrigerant circuit.
• Install Difficulty: 2/5 — Turn off power at both the breaker and disconnect before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, and a non-contact voltage tester. Always photograph all wiring terminals before disconnecting. Reconnect line-voltage leads (L1/L2) to top terminals and load leads (T1/T2) to bottom.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cut-off.

Compatibility: Engineered as the direct OEM replacement for Carrier model 09DE064510. Verify coil voltage (120V) and amperage (30A) against your unit's data plate before ordering — do not substitute a 24V coil version for this application. Have questions about fitment?
