OEM Carrier Single-Pole Contactor 30A 24V Coil (HN51KC024) for Model PY4GNAB36060NA

This is the genuine OEM Carrier contactor (part number HN51KC024), the factory-specified high-voltage switching relay for the Carrier PY4GNAB36060NA packaged unit. The contactor acts as the main power switch for the compressor and/or condenser fan motor — energized by the 24V control circuit every time the thermostat calls for cooling. When the contactor fails, the most common symptom is an AC unit that receives a thermostat call but simply will not turn on; you may also experience welded or pitted contacts that keep the system running continuously even after the call ends, driving up energy costs and risking compressor damage.

• Specs: 1-Pole | 30A Full Load Amps (FLA) / 150A Locked Rotor Amps (LRA) | 24 VAC Coil | 50/60 Hz | Factory OEM part number HN51KC024
• OEM vs Generic: Genuine Carrier Factory Authorized Parts are engineered to exact Carrier specifications for proven reliability and proper contact gap tolerances. Generic contactors may use lower-grade contact alloys, leading to premature pitting, coil burnout, and shortened service life under high-cycle loads.
• 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. Photograph all wiring before removal. Discharge any residual voltage, transfer line, load, and 24V coil leads to the new contactor terminal-for-terminal, then verify pull-in with a live 24V thermostat call.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.
