York 024-35467-000 Contactor

The York 024-35467-000 Contactor is a heavy-duty, 3-pole definite purpose contactor engineered for high-current HVACR applications. Rated at 65 Amps, this genuine OEM York part is critical for switching line voltage to large 3-phase compressors and motors in commercial chillers and packaged units. Constructed for longevity, this industrial-grade electrical switch features a 24V coil voltage, ensuring seamless integration with standard low-voltage control circuits. When replacing a worn 65A 3-pole contactor, precision in FLA ratings and coil voltage compatibility is paramount to prevent coil burnout or contact welding. This unit is designed to handle the inductive load of high-tonnage equipment, providing reliable cycling and protecting sensitive downstream components from electrical arcing. For technicians performing system diagnostics, the robust housing and terminal design facilitate secure electrical connections and efficient heat dissipation under continuous duty cycles.

Key Benefits

• 65 Amp High-Load Capacity: Built to manage the significant amp draw of commercial 3-phase compressors and motor loads without overheating.
• OEM Precision: Guaranteed direct replacement compatibility for specific York and Johnson Controls equipment, eliminating the need for field modifications.
• Rugged 3-Pole Construction: Provides simultaneous switching of all three power legs to ensure balanced voltage delivery and prevent single-phasing motor failures.
• Standard 24V Control: Features a reliable electromagnetic coil designed for standard low-voltage HVAC control boards.

Common Questions

Can I use a contactor with a higher Amp rating than the original?
Yes, as long as the coil voltage and the number of poles match, using a contactor with a higher FLA rating is acceptable and often increases the lifespan of the contacts. Never use a lower Amp rating than the system's plate data requires.

Why did my previous contactor coil burn out?
Coil failure is often caused by low voltage (voltage drop) from the transformer, moisture intrusion, or excessive debris (like ants) preventing the armature from fully seating, which increases the inductance and heat in the coil winding.

How do I test a 3-pole contactor for pitting?
With the power disconnected, inspect the contacts for heavy carbon deposits or "welding." You can also check for high resistance across the closed contacts using a multimeter; any reading above 0.1 to 0.3 ohms typically indicates the need for replacement.
