OEM Carrier Contactor 2-Pole 24V Coil for Model 09DE054510

This OEM replacement contactor (part number HN52KC052) is the factory-specified high-voltage relay for Carrier 09DE054510 systems. The contactor acts as the primary switching device that connects utility-level voltage to your compressor and condenser fan motor whenever the thermostat calls for cooling. When it fails, the most common symptoms include an air conditioning system that won't turn on at all, a unit that hums continuously without starting, or burnt/pitted contact points visible on inspection. Replacing a worn contactor promptly protects your compressor — the most expensive component in the system.

• Specs: 2-pole configuration | 24V AC coil voltage | Factory-rated amperage | OEM-matched contact material for reduced arcing and extended service life
• OEM vs Generic: This is a genuine OEM Carrier contactor built to exact factory specifications. Generic aftermarket contactors often use lower-grade contact alloys that pit and burn faster, leading to premature compressor failure and repeat service calls.
• Install Difficulty: 2/5 — Always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal to ensure correct reinstallation.
