York 024-37039-000 Contactor
The York 024-37039-000 Contactor is a professional-grade 3-pole HVAC contactor engineered for heavy-duty electrical load switching in industrial and commercial climate control systems. This 40-amp contactor utilizes an 110V AC coil (also compatible with 120V circuits) to manage high-current components such as compressors, condenser fans, and blower motors. Built to withstand rigorous duty cycles, the S1-024-37039-000 features high-conductivity silver alloy contacts that minimize arcing and prevent oxidation, ensuring reliable connectivity under load. As a direct OEM York replacement part, it guarantees precise mechanical alignment within HVAC control panels, allowing for efficient field installation and restoration of three-phase power distribution circuits. For technicians servicing York, Johnson Controls, or Unitary Products equipment, this contactor provides the necessary amperage overhead and insulation ratings to maintain system uptime in demanding environments.
Key Benefits- Enhanced Durability: Equipped with industrial-grade silver alloy contacts to extend service life and improve electrical conductivity.
- OEM Compatibility: Designed as a genuine S1-024-37039-000 replacement to ensure exact fitment in York and Johnson Controls units.
- High Amperage Capacity: Rated for 40 amps to safely manage the inductive loads of larger 3-phase HVAC motors and compressors.
- Reliable Coil Performance: The 110V/120V AC coil provides consistent pull-in voltage, reducing the risk of contact chatter or drop-out.
What is the difference between this 3-pole contactor and a single-pole version?
This 3-pole contactor breaks all three lines of a three-phase power supply simultaneously, which is required for 3-phase HVAC equipment to ensure complete circuit isolation during the off-cycle.
Can I use an 024-37039-000 if my current contactor has a 24V coil?
No. The coil voltage must match your control circuit. This specific model requires a 110V-120V control signal; using a 24V signal will not provide enough force to close the contacts.
How do I know if the contacts on my 40-amp contactor are failing?
Check for visible pitting, charring, or "welded" contacts. Excessive voltage drop across the poles or significant humming from the coil are also primary indicators that a replacement is necessary.
