York S1-024-25840-700 Contactor

The York S1-024-25840-700 is an OEM 2-pole magnetic contactor engineered for heavy-duty HVAC compressor control and motor switching. Supporting a 40 amp current rating and 1.0 inductive load, this electrical component is specifically designed for 24V control circuits, ensuring precise actuation of high-draw system loads. As the direct replacement for S1-024-25840-000, it maintains original equipment standards for form factor and terminal alignment, reducing downtime during field installation. The normally open (2PNO) contact configuration and panel-mount design make it a reliable choice for supervising power to fans, compressors, and resistive heating elements in York, Luxaire, and Coleman package units and split systems.

Key Benefits

• Broad Compatibility: Serving as a universal York 24V coil contactor, this part replaces discontinued models like S1-024-25840-000 without technical modification.
• High Amperage Rating: Rated for 40A FLA (Full Load Amperage), providing the necessary overhead for demanding industrial and residential air conditioning units.
• Reliable Switching: The silver-cadmium oxide contacts minimize arcing and pitting, extending the service life of high-voltage components.
• Standardized Mounting: Features a flexible mounting base that fits existing screw patterns in standard electrical control cabinets.

Common Questions

Can I use this contactor for a 40A inductive load?
Yes, this 40 amp HVAC contactor is rated for 40A inductive and 50A resistive loads, making it ideal for large tonnage compressors and heat pump applications.

Does this replace a 1-pole contactor?
While a 2-pole contactor like the S1-024-25840-700 can physically replace a 1-pole model by switching both lines, you should always verify the original wiring schematic to ensure proper circuit isolation and safety compliance.

What causes a 24V coil to chatter or fail?
Coil chatter is typically caused by low voltage or loose connections at the thermostat or control board. Ensure a steady 24V signal to the coil to prevent contact welding.
