York 024-34302-000 Contactor

The York 024-34302-000 is an OEM-spec 3-pole contactor built for high-demand HVACR applications. For contractors, pull-in reliability is critical; this unit utilizes a 110V coil to drive industrial-grade silver cadmium oxide contacts rated for 25 Amp inductive loads. Its 3P configuration provides full break control for three-phase compressors and motors, ensuring your circuitry is fully isolated when the thermostat de-energizes the coil. The integrated auxiliary contact (W/AUX) allows for seamless integration of status feedback or interlocking secondary components like crankcase heaters and fan cycles. When replacing a scorched HVAC contactor, physical footprint and terminal orientation matter; this genuine York component fits standard mounting brackets without modification. Designed to withstand 600V AC peaking, this magnetic contactor eliminates the pitting and welding issues common with generic aftermarket replacements, ensuring consistent arc suppression and mechanical longevity in the field.

• OEM Compatibility: Exact replacement for York and Johnson Controls equipment, direct cross-reference for part 208R89.
• Full Load Capacity: Rated for 25 Amps, providing the overhead needed for residential and light commercial compressors.
• Enclosure & Auxiliary: Includes a factory-mounted auxiliary switch for additional circuit logic and control.
• Industrial Durability: Robust 3-pole construction designed for high cycle counts and reliable switching under thermal stress.

Can I use this 110V coil contactor in a 24V system?
No. The 024-34302-000 requires a 110V-120V control signal to energize the coil. Using it in a 24V control circuit will prevent the contacts from pulling in.

What is the purpose of the auxiliary contact on this unit?
The auxiliary contact is used to signal a control board or interlock other equipment, ensuring that secondary components only operate when the main 3-pole contacts are engaged.

When should I replace a 3-pole HVAC contactor?
Replace the unit if you find pitted contacts, a humming 110V coil, or if the contacts have welded shut, which causes the compressor to run continuously.
