The contactor is the high-voltage relay that responds to a 24V signal from the thermostat or control board and closes the circuit to deliver line voltage to the compressor and condenser fan motor. When the contactor fails — due to pitted or burned contacts, a welded contactor, or a failed coil — your system will either refuse to turn on entirely, run continuously without shutting off, or trip the breaker repeatedly.
