OEM Carrier 1-Pole 30 Amp 24V Contactor (HN51KC024) for Model PH13NA03600GABAA

This is the factory-specified OEM contactor for the Carrier PH13NA03600GABAA heat pump / air conditioning system. The contactor is the high-voltage relay that closes the compressor and condenser fan motor circuit every time your thermostat calls for cooling or heating. When it fails, the system may fail to start entirely, run continuously and refuse to shut off, or produce an audible chattering or humming from the outdoor unit. Pitted, burned, or welded contacts are the most common causes of all three failure modes.

• Specs: 1-Pole | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50/60 Hz rated | OEM part number HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part engineered to exact factory specifications. Generic contactors often use lighter contact materials that pit and weld faster under the high-inrush loads of R-410A scroll compressors, leading to premature failure.
• Install difficulty: 2/5 — Shut off power at both the breaker and the disconnect before touching any wiring. Photograph all wire positions before disconnecting. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter to verify 24V coil pull-in after installation.
• Warranty & Shipping: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
