OEM Carrier 2-Pole Contactor 24V Coil for Model FIOP200501GA — HN51KC024

This OEM contactor (part number HN51KC024) is the factory-specified high-voltage relay for the Carrier FIOP200501GA packaged or split-system unit. The contactor acts as the main power switch for the compressor and condenser fan motor, closing its contacts when the 24V control circuit signals a call for cooling. When the contactor fails — due to burned or pitted contacts, a welded contact that won't release, or a failed coil — the system may not turn on at all, run continuously without shutting off, or trip the breaker repeatedly.

• Specs: 2-pole configuration | 24V AC coil voltage | Heavy-duty contact rating | Factory-matched to Carrier FIOP200501GA electrical specifications
• OEM vs Generic: This is a genuine OEM Carrier contactor manufactured to exact factory specifications. Generic contactors often use lighter contact materials that pit and burn faster under compressor load, shortening service life significantly in high-cycle applications.
• Install difficulty: 3/5 — High-voltage component; always disconnect power at the breaker and verify zero voltage with a multimeter before touching any terminals. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring connections before removal.
