OEM Carrier Single-Pole Contactor 1-Pole 30A 24V for Model PH13NR04200GAHAA — HN51KC024

This OEM Carrier contactor (part number HN51KC024) is the factory-specified replacement for the Carrier PH13NR04200GAHAA heat pump condenser unit. The contactor is the high-voltage switching relay that bridges 240V power to the compressor and condenser fan motor whenever the 24V thermostat circuit calls for cooling or heating. When the contactor fails, symptoms include the outdoor unit not starting despite a thermostat call, a persistent humming or chattering sound from the control box, or the unit running continuously and refusing to shut off — all signs of pitted, welded, or burned contacts.

• Specs: 1-Pole | 30A FLA / 150A LRA | 24 VAC coil voltage | 50/60 Hz | Screw terminal connections | R-410A system compatible
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact OEM specifications for the PH13NR04200GAHAA. Generic contactors often use lower-grade contact alloys that pit faster under repeated switching, reducing service life and risking compressor damage.
• Install difficulty: 2/5 — Disconnect and lock out all power at the breaker before opening the control panel. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Verify 24V coil pull-in after installation with a thermostat call.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.
