The contactor acts as the high-voltage switching relay that energizes the compressor and condenser fan motors each time the thermostat calls for cooling. When the low-voltage control circuit closes the contactor coil, the main contacts snap shut and deliver line voltage to the condensing section. A failed contactor will leave your system dead on a call for cooling, chattering loudly, or — in the case of welded contacts — running non-stop even after the thermostat is satisfied.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 3-Pole | 208-240V coil | 40 FLA \/ 50A RES | Definite-purpose design | Factory-matched contact gap and spring tension for reliable pull-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM contactors are built to Carrier's exact coil impedance and contact material specs.
