Daikin-McQuay Contactor Coil HVAC Relay

Daikin-McQuay contactor coil HVAC relays are OEM replacement control components for commercial heating, cooling and ventilation equipment. A contactor or relay coil is the electromagnet that closes the switching contacts when the control circuit is energized. That lets the circuit send power to compressors, fan motors, blower motors and other loads in air handlers, rooftop units and chillers. When a coil or relay wears out, the equipment can short-cycle, chatter or fail to start. Replacing it restores proper switching.

Key Features:

• Genuine Daikin-McQuay replacement parts built to match factory electrical specifications for Daikin and McQuay equipment
• Electromagnetic coil design that pulls in the contacts when the control circuit is energized
• Durable contacts and housings made to handle repeated cycling and inductive loads such as motors and compressors
• Standard terminals for secure wiring and straightforward troubleshooting
• Available in a range of coil voltages, pole configurations and ratings for different control circuit requirements

Daikin-McQuay has made commercial HVAC equipment for decades, and these parts are made to keep that equipment running reliably. Select the child item whose coil voltage, pole count and amperage rating match the component you are replacing. Always disconnect power before servicing electrical components.
