York S1-024-35802-000 Contactor

The York S1-024-35802-000 Contactor is a heavy-duty electrical component engineered for demanding HVACR applications. This 3-pole contactor features a 24V coil and is rated for 75 amp resistive loads, making it a reliable solution for high-capacity condenser units and commercial refrigeration systems. Designed as a definite purpose contactor, it facilitates the switching of power to compressors and fan motors with minimal arc erosion, ensuring long-term performance under frequent cycling conditions. The magnetic contactor design utilizes high-conductivity materials to reduce resistance and heat buildup during extended operation.

When replacing a failed HVAC contactor, technicians prioritize the S1-024-35802-000 for its precise fit and technical compatibility with York, Source 1, and Johnson Controls equipment. The 3P 75A contactor architecture ensures that all three legs of power are managed simultaneously, protecting downstream components from single-phasing issues. This York replacement part is built to handle the high inrush currents typical of large inductive motor loads, providing a robust interface between the low-voltage thermostat signal and the high-voltage system power.

• High Ampacity Rating: Rated for 75 amps to support heavy-duty commercial and residential HVAC units.
• Reliable 24V Coil: Ensures seamless integration with standard 24VAC control circuits and thermostats.
• Three-Pole Configuration: Provides simultaneous switching for 3-phase equipment or multi-leg power isolation.
• Definite Purpose Build: Specifically designed to withstand the thermal stress and electrical arcing of motor-starting applications.
• OEM Compatibility: Precision-engineered as a direct York S1-024-35802-000 replacement to ensure proper mounting and terminal alignment.

What are the signs of a failing 75 amp contactor?
Technicians should look for pitted contacts, burnt terminal lugs, or a "chattering" sound. If the 24V coil is energized but the contacts do not close, or if the system won't shut off, the contactor likely has welded points or a failed coil.

Can I use this contactor as a replacement for a 60 amp model?
Yes, you can typically "up-rate" a contactor as long as the coil voltage (24V) and the number of poles match. Using a 75 amp contactor to replace a lower-rated unit provides a larger surface area for the contacts, which can improve durability under load.

Does this 3-pole contactor work for single-phase systems?
While designed for 3-pole applications, it can be used in single-phase systems by utilizing only the required poles, though a standard 1 or 2-pole unit may be more common for those specific configurations.
