OEM Carrier 2-Pole 30 Amp 120V Contactor HN52KC052 for Model 09DE084C910

This OEM Carrier contactor (part number HN52KC052) is the factory-specified high-voltage relay for the Carrier 09DE084C910 system. The contactor acts as the main electrical switch that energizes the compressor and condenser fan motor each time the thermostat calls for cooling. When the contactor fails — due to worn contacts, pitting, or a burned-out coil — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker. Replacing it with the correct OEM part ensures reliable switching and protects downstream components from voltage irregularities caused by a degraded aftermarket substitute.

• Specs: 2-pole | 30 Amp | 120V coil voltage | 50/60Hz rated | Factory OEM part number HN52KC052
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact contact gap, spring tension, and coil pull-in tolerances. Generic contactors often use thinner contact material, leading to premature pitting and arc-welding of contacts — a common callback issue for technicians.
• Install difficulty: 3/5 — Disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V coil signal and confirm dead contacts before replacement). Photograph all wiring before disconnecting. This is a 120V coil contactor — verify coil voltage on the existing unit's data plate before ordering.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed as the direct OEM replacement contactor for Carrier model 09DE084C910.
