Daikin-McQuay CONT2P040024DS 2-Pole 40 Amp 24VAC Definite Purpose Contactor

The Daikin-McQuay CONT2P040024DS is a 2-pole, 40-amp definite purpose contactor with a 24VAC coil, designed for use in residential and light commercial HVAC systems. Contactors of this type serve as electrically operated switches that control power flow to major components such as compressors and condenser fan motors in air conditioning and heat pump equipment.

When the system's control board issues a low-voltage signal, the contactor coil energizes and closes the high-voltage circuit, delivering power to the condensing unit. This makes the contactor a critical component in HVAC operation — a failed contactor will prevent the condensing unit from receiving power entirely.

Key Specifications:

• Poles: 2-Pole
• Amperage: 40 Amps
• Coil Voltage: 24VAC
• Type: Definite Purpose Contactor
• Replaces: CONT2P040024VS

Key Features:

• Direct OEM replacement — installs without modification
• Low-voltage (24VAC) coil control for compatibility with standard HVAC thermostat circuits
• 2-pole design switches both legs of the load simultaneously for safe, reliable operation
• Enclosed contact design for durability and protection
• Suitable for compressor and condenser fan motor load switching in split-system AC and heat pump applications

This contactor is a proven, reliable replacement for worn or failed contactors in Daikin, McQuay, Goodman, and Amana HVAC equipment. To verify a failed contactor, use a multimeter to test for continuity across the load contacts with the coil energized. Replace if continuity is absent.
