OEM Carrier 1-Pole 30 Amp 24V Contactor for Model PH13NR04800GACAA — HN51KC024

This is the factory OEM contactor for the Carrier PH13NR04800GACAA heat pump. The contactor is the high-voltage relay that closes when the 24V thermostat signal calls for cooling or heating, allowing line voltage to reach the compressor and condenser fan motor. When it fails — due to pitted or burned contacts, a shorted coil, or contacts welded shut — your system will either refuse to start at all, run continuously without shutting off, or trip the breaker. Replacing this part restores proper on/off switching and protects expensive downstream components like the compressor.

• Specs: 1-Pole | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This genuine Carrier OEM contactor is manufactured to exact factory tolerances for contact gap, coil pull-in voltage, and silver-alloy contact material. Generic aftermarket contactors often use lower-grade contact alloys that pit and fail faster, especially under the high inrush currents of a compressor start.
• Install difficulty: 2/5 — Disconnect and lock out all power before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring connections before removal. Discharge any capacitors in the same cabinet before reaching in. Verify 24V coil pull-in with a thermostat call after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
