Carrier HK02ZA442 Pressure Switch
The Carrier HK02ZA442 Pressure Switch is a critical safety component engineered for precise high-pressure cut-out in Carrier, Bryant, and Payne residential and commercial systems. This genuine OEM replacement part is calibrated for a 448 PSI open and 327 PSI close threshold, ensuring the compressor is protected from over-pressurization during demanding cooling or heating cycles. As a direct HK02ZA442 high pressure switch, it serves as the official cross of HK02ZA428, providing a drop-in fit for technicians servicing 580F, 580T, and 581B series models. This switch monitors the refrigerant line and interrupts the control circuit if pressures exceed safe operating limits, preventing catastrophic equipment failure. Built with high-grade materials to withstand vibration and thermal cycling, this industrial pressure control maintains system integrity and ensures long-term operational reliability in heat pump and air conditioning applications.
Key Benefits
- Direct OEM Compatibility: Engineered as a genuine replacement for Carrier HK02ZA442 and legacy part number HK02ZA428.
- Precise Field Performance: Factory-calibrated 448# Open / 327# Close specifications ensure accurate system response without the need for field adjustments.
- Critical System Protection: Safeguards expensive compressors and internal components from high-side pressure spikes.
- Robust Construction: Designed to handle the rigorous duty cycles typical of commercial HVAC high pressure safety applications.
Common Questions
Is the Carrier HK02ZA442 a manual or automatic reset switch?
This model is typically an automatic reset switch that closes the circuit once the high-side pressure drops below the 327 PSI threshold, allowing the system to resume normal operation safely.
Can I use this to replace part number HK02ZA428?
Yes, the HK02ZA442 is the cross of HK02ZA428, meaning it is the manufacturer-recommended updated replacement with identical technical specifications.
What systems are compatible with this high pressure switch?
It is commonly utilized in Carrier models such as the 580FPV102224AB, 580FTV121250AA, and 581BPV072150AH, as well as various other package units and heat pumps requiring a 448 PSI cut-out.
