York S1-024-24101-700 Contactor

The York S1-024-24101-700 is a field-ready 2-pole contactor designed for high-reliability switching in residential and light commercial condensing units. This component is the primary technical equivalent for the 3100-20Q315, specifically engineered to handle a 20 Amp inductive load. Operating on a standard 24V coil voltage, the 2PNO (2-Pole, Normally Open) configuration ensures that both legs of the power supply are disconnected during the off-cycle, reducing the risk of motor winding degradation and improving overall system safety. The contactor features silver cadmium oxide contacts to provide superior resistance to pitting and welding under high-cycle conditions. Its universal mounting base and compact footprint allow for seamless integration into existing control boxes, while the combination of screw terminals and quick-connect spade lugs simplifies field wiring. Whether you are performing a routine service or a critical repair, this HVAC contactor provides the precise mechanical switching necessary for optimal compressor and fan motor performance.

Key Benefits

• Direct replacement match for York, Luxaire, and Coleman 3100-20Q315 specifications.
• Heavy-duty 20 Amp rating suitable for a wide range of residential split systems.
• Encapsulated 24V coil designed to resist environmental debris and moisture.
• Two-pole break configuration ensures complete electrical isolation of downstream components.

Common Questions

What is the coil voltage required for the S1-024-24101-700?
This contactor uses a 24V AC control circuit. It is not compatible with 120V or 240V control signals.

Can this contactor replace a 30 Amp rated unit?
No, this model is rated for a maximum of 20 Amps inductive. Always check the Full Load Amps (FLA) on the equipment nameplate before installation to ensure the load does not exceed the contactor rating.

Does this unit switch one or two legs of power?
This is a 2-pole (2PNO) contactor, meaning it mechanically switches both legs of the incoming power supply simultaneously.
