OEM Carrier 1-Pole 30 Amp Contactor HN51KC024 for Model PH16NA02400GBBAA

This is the factory OEM contactor for the Carrier PH16NA02400GBBAA heat pump. The contactor is the high-voltage switching relay that closes when the thermostat sends a 24V signal, connecting line voltage to the compressor and/or condenser fan motor. When it fails — due to pitted or burned contacts, a stuck plunger, or a failed coil — your outdoor unit will not energize at all, or may run continuously without shutting off. Replacing the contactor is one of the most common and cost-effective HVAC repairs available.

• Specs: 1-Pole configuration | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 24 VAC coil voltage | 50/60 Hz | OEM Part# HN51KC024
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact factory tolerances. Generic contactors may use thinner contact material that pits faster under compressor load cycling, leading to premature failure and potential compressor damage.
• Install difficulty: 2/5 — Shut off all power at the disconnect and breaker before beginning. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter. Photograph all wiring before disconnecting terminals. Verify 24V coil pull-in with a meter after installation before restoring power.
