OEM Carrier 2-Pole 120V 30 Amp Contactor HN52KC052 for Model 09DE146600

This OEM contactor is the factory-specified replacement for the Carrier 09DE146600. The contactor serves as the high-voltage relay that connects and disconnects line voltage to the compressor and condenser fan motor every time your system calls for cooling. When this component fails, you'll typically notice the system failing to start, a persistent buzzing or chattering noise from the outdoor unit, or — in the case of welded contacts — the compressor running continuously even when the thermostat is satisfied.

• Specs: 2-Pole | 120V Coil | 30 Amp | 50/60Hz | Factory OEM part number HN52KC052 — direct drop-in replacement with no modifications required.
• OEM vs Generic: OEM contactors are manufactured to Carrier's exact coil pull-in voltage, contact gap, and arc-suppression specifications. Generic contactors may chatter at low voltage and cause premature compressor wear — always choose OEM for critical switching components.
• Install difficulty: 3/5 — Disconnect all power at the breaker AND the disconnect block before proceeding. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 0V before touching terminals). Photograph all wiring before removal. Coil terminals are 24V; line terminals carry up to 240V — exercise caution.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our NationalHVACParts.com warehouse.
