The contactor is the high-voltage relay that receives a low-voltage (24V) signal from the thermostat and closes the circuit to energize the compressor and\/or condenser fan motor. When the contactor fails — due to worn contacts, pitting, coil burnout, or welded contacts — the system will either fail to start entirely, run continuously without shutting off, or trip the breaker. A failed contactor is one of the most common causes of a no-cooling call in the field.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 1-Pole configuration | 24 VAC coil voltage | 30A Full Load Amps (FLA) | 150A Locked Rotor Amps (LRA) | 50\/60 Hz | OEM Part# HN51KC024\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, manufactured to exact OEM tolerances.
