OEM Carrier 2-Pole Contactor 40 Amp 24V Coil for Model TCHC2550HECMRAY602

This OEM contactor (part #HN52TC040) is the factory-specified high-voltage relay for the Carrier TCHC2550HECMRAY602 system. The contactor acts as the primary electrical switch that closes the high-voltage circuit to your compressor and condenser fan motor every time the thermostat calls for cooling. When the contactor fails, you'll typically find the outdoor unit completely unresponsive — the system won't turn on at all, or it may hum under load with no mechanical response. Burned or pitted contacts, a coil that won't pull in on 24V, and premature compressor cutout are all classic signs this part needs replacement.

• Specs: 2-Pole | 40 FLA (Full Load Amps) | 24V 50/60Hz coil | 240/277V load side | Factory OEM part #HN52TC040
• OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory specifications. Generic contactors often use lower-grade contact materials that pit and erode faster under repeated switching, leading to premature failure and compressor damage.
• Install difficulty: 2/5 — Always shut off power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wire connections before removal. Discharge any residual capacitor voltage nearby before touching terminals.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.
