OEM Carrier 2-Pole 40A 24V Contactor HN52TC040 for Model TCHC0250HEFMRAF601

This is the OEM factory-specified replacement contactor for the Carrier TCHC0250HEFMRAF601 heat pump and HVAC systems. The contactor is a high-voltage relay that receives a 24V signal from the thermostat and closes to supply 208–230V power to the compressor and condenser fan motor. When it fails, the outdoor unit will not energize at all, or may hum and chatter without fully closing — symptoms that can also lead to compressor damage if left unaddressed.

• Specs: 2-Pole | 40A FLA | 24V AC Coil | 208–230V Switching Voltage | 50/60 Hz | Single Phase | OEM Part# HN52TC040
• OEM vs Generic: This is a genuine Carrier OEM contactor built to exact factory tolerances. Generic contactors often use lower-grade contact materials that pit and weld faster under load, shortening service life significantly.
• Install Difficulty: 2/5 — Always disconnect power at the disconnect box and verify voltage is absent before touching any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before removal.
• Warranty: 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse.

Compatibility: Designed for the Carrier TCHC0250HEFMRAF601 heat pump system.
