York S1-024-25839-700 Contactor

The York S1-024-25839-700 is an OEM-grade 120V 30A contactor engineered for reliable switching in high-demand HVACR environments. This 2-pole normally open (2PNO) component is designed to manage inductive loads for compressors and fan motors in residential and light commercial units. As a direct technical equivalent to the 3100Y20T615, it ensures precise mechanical alignment and electrical compatibility during field installation. The unit features silver cadmium oxide contacts to provide superior conductivity and resistance to pitting under high-cycling conditions. With a 120V coil configuration, this HVAC replacement part is the standard for service technicians maintaining York, Luxaire, and Coleman equipment. Its robust frame and industry-standard mounting bracket facilitate a fast swap-out in control cabinets, ensuring the system operates at peak electrical efficiency without the risk of chatter or premature contact welding. This contactor is a critical component for restoring circuit integrity in systems requiring 30-amp switching capacity.

Key Benefits for Technicians:

• Universal Compatibility: Field-ready replacement for the 3100Y20T615 across multiple brand platforms.
• Durable Construction: Built with high-grade terminal lugs and a dust-shielded housing to prevent debris-related failure.
• Optimized Performance: Specifically rated for 30 Amp full load applications to ensure stable power delivery to the compressor.
• Efficient Installation: Standard footprint and accessible wiring terminals reduce labor time during service calls.

Common Technical Questions:

Can the S1-024-25839-700 be used in a 24V control circuit?
No, this specific model is equipped with a 120V coil. Utilizing it in a 24V system will prevent the contacts from pulling in. Always verify coil voltage before installation.

Is this contactor suitable for 40 Amp loads?
This component is rated for a maximum of 30 Amps. For systems requiring a higher amperage draw, you must use a contactor rated for the specific FLA (Full Load Amperage) of the equipment.

Will this replace a single-pole contactor?
While it can technically replace a single-pole unit of the same amperage and coil voltage, this is a 2-pole contactor that breaks both sides of the power line, increasing safety by ensuring no residual voltage remains at the load when the contactor is open.
