York S1-024-25964-000 Contactor

The York S1-024-25964-000 Contactor is a critical OEM replacement component designed for high-reliability switching in residential and light commercial HVAC systems. This 1-pole magnetic contactor features a 24V AC coil and is rated for a 20 FLA (Full Load Amperage) capacity, making it the standard specification for managing compressor and condenser fan motor loads. The integrated shunt provides a continuous electrical path for the neutral or secondary line, simplifying field wiring and reducing the footprint within the control box.

Engineered for longevity, the York S1-024-25964-000 utilizes silver-cadmium oxide contacts to resist welding and pitting under high-inrush startup conditions. This single pole contactor is a direct replacement for legacy York part number 024-25842-000 and is compatible with a wide range of BACB, BAUA, and BPGM series units. Its compact frame and standard mounting bracket ensure seamless integration for service technicians performing rapid field repairs. When replacing a failed contactor, this OEM part maintains the original equipment’s electrical characteristics and safety ratings.

• OEM Compatibility: Guaranteed fit for York, Luxaire, and Coleman equipment, replacing part 024-25842-000.
• Efficient Design: Integrated shunt simplifies single-phase wiring by providing a permanent bridge for the common side.
• Durable Construction: Rated for 20A FLA and 30A Resistive loads, ensuring stable performance in extreme ambient temperatures.
• Standardized Control: Universal 24V coil works with standard HVAC transformers and digital thermostats.

What does the shunt do in a 1-pole contactor?
The shunt provides a permanent electrical connection for one side of the line, meaning only the other side is physically interrupted by the contact points. This is standard in single-phase HVAC equipment to feed power to the crankcase heater or other constant-power components.

Can I use a 30A contactor to replace this 20A model?
While a higher amperage rating is generally acceptable, maintaining the OEM 20A specification ensures the component matches the internal fusing and wire gauge protection designed by the manufacturer.

Will this work with 208/230V systems?
Yes, the load side (contacts) can handle up to 240V, but the control side (coil) must be energized by a 24V AC circuit.
