OEM Carrier Single-Pole Contactor 30 Amp 24V Coil (HN51KC024) for Model PY3GNAA36060NA

This is the genuine OEM factory-specified single-pole contactor for the Carrier PY3GNAA36060NA packaged or split-system HVAC unit. The contactor is the high-voltage switching relay that closes the compressor and/or condenser fan motor circuit whenever the 24V thermostat calls for cooling. When it fails — due to pitted contacts, a welded coil, or an open winding — you'll experience symptoms like the system humming but not starting, the outdoor unit failing to energize, or the unit tripping on high pressure with no compressor activity. Replacing with the OEM part ensures factory-matched contact pressure, coil pull-in voltage, and long-term reliability.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | Part # HN51KC024
• OEM vs Generic: OEM contactors are manufactured to Carrier's exact contact gap and coil resistance tolerances. Generic contactors often use lighter contact material that pits and welds faster under compressor inrush current, reducing service life significantly.
• Install Difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Photograph all wiring before removing any terminals. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 24V coil pull-in after install). Always confirm the contactor pulls in fully with a thermostat call before closing the unit.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
