Daikin-McQuay Definite Purpose Contactor Contactors

Daikin-McQuay definite purpose contactors are electrical switching components for HVAC systems. They are also called HVAC contactors or air conditioner contactors. A contactor uses a low-voltage control signal from the thermostat or control board to open and close the higher-current circuit that powers a compressor, condenser fan motor, or other load in air conditioning and heat pump equipment.

Key Features:

• Definite purpose design built for the repeated switching of HVAC and refrigeration loads
• Electromagnetic coil that closes the contacts when the control circuit is energized
• Pole, voltage, and amperage ratings vary by part number, so you can match the contactor to your equipment's electrical requirements
• Replacement part from Daikin-McQuay, a recognized name in commercial and residential HVAC equipment

Choose the variant that matches the pole count, coil voltage, and current rating of the contactor you are replacing. Always disconnect power before servicing any HVAC electrical component.
