York 025-28985-002 Pressure Switch

The York 025-28985-002 is a high-performance 405/330# High Pressure Switch designed for critical system protection in commercial and residential HVAC units. Engineered to monitor discharge line dynamics, this auto-reset pressure switch features a 405 PSI cut-out and a 330 PSI cut-in, ensuring that the compressor is immediately deactivated when pressure exceeds safe limits. This specific York pressure switch is a direct OEM replacement part for a range of York, Luxaire, and Coleman equipment, including YCAJ series chillers and various air conditioning split systems. Built with a rugged brass housing, it provides reliable electrical switching at 24V AC, maintaining system integrity even in hostile operating environments with temperatures ranging from -30°C to 65°C.

• Precise Pressure Calibration: Factory-set 405 PSI trip point and 330 PSI reset point eliminate the need for field adjustment and prevent high-limit cycling.
• OEM Compatibility: Replaces part numbers 025-28985-002, S1-025-28985-002, and SWT-4900 for a perfect fit in York YCAJ150 through YCAJ230 models.
• Enhanced Equipment Lifespan: Protecting the compressor from excessive head pressure prevents mechanical fatigue and catastrophic secondary failures.
• Industrial-Grade Construction: Features a durable brass body and high-conductivity contacts to handle 24V and 240V control circuit applications.

Is this an automatic or manual reset switch?
This is an automatic reset pressure switch. It will cut out at 405 PSI and automatically reset and close the circuit once the pressure drops back down to 330 PSI.

Which refrigerant systems is this switch compatible with?
The York 025-28985-002 is typically utilized in high-pressure R-410A systems but can be found in various applications where the 405/330 PSI setpoints are required for high pressure cut-out protection.

What are the electrical ratings for this part?
The switch is rated for standard 24V AC control circuits but is built with heavy-duty internal components capable of handling up to 240V AC for specific industrial applications.
