OEM Carrier 2-Pole Contactor 40 Amp 24V Coil for Model TCHC2550HECMRAY901

This is the genuine OEM Carrier contactor (part number HN52TC040), factory-specified for the Carrier TCHC2550HECMRAY901 heat pump and condenser system. The contactor is the high-voltage relay that bridges 24V thermostat control signals to the 240V power circuit, energizing the compressor and condenser fan every time a cooling or heating call is made. When a contactor fails — through burned contacts, a seized coil, or welded poles — the system will either refuse to turn on entirely, fail to shut off, or cycle erratically. Replacing with the correct OEM unit restores factory-spec switching performance and protects downstream compressor components.

• Specs: 2-Pole | 40 FLA (Full Load Amps) | 24V 50/60Hz coil voltage | Direct-mount OEM replacement | Factory-matched contact gap and coil pull-in voltage
• OEM vs Generic: OEM Carrier contactors use precision-rated contacts calibrated to the exact switching load of the TCHC2550HECMRAY901. Generic contactors often use lower-grade contact materials that arc and pit faster, shortening compressor life and increasing nuisance lockouts.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Always photograph terminal wiring before disconnecting leads to ensure correct re-termination.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.
