Carrier HK02ZA436 Pressure Switch
The Carrier HK02ZA436 is a professional-grade high pressure switch engineered for critical refrigerant monitoring in industrial refrigeration and air conditioning systems. As an essential safety component, this HVAC pressure switch features a 290 PSI cutout and a 185 PSI cut-in, providing a precise 290/185 pressure range. When system pressure exceeds the preset limit, the switch breaks the electrical circuit to the compressor, preventing catastrophic equipment failure and ensuring safe operational parameters.
Constructed with a rugged housing to withstand demanding field conditions, the HK02ZA436 is a genuine Carrier OEM part designed for seamless integration into existing control logic. This compact device monitors refrigerant gas pressure and provides reliable mechanical protection without the need for complex calibration. For field technicians, this refrigerant pressure regulator is a primary defense against high-head pressure issues caused by condenser fan failure or system blockages.
Key Benefits
- Precision Pressure Control: Features a factory-set 290 PSI open (cutout) and 185 PSI close (cut-in) for consistent system protection.
- OEM Compatibility: Designed specifically for Carrier and Bryant HVAC equipment to ensure exact electrical and mechanical fit.
- Industrial Durability: Built with high-quality internals to handle the vibrations and thermal cycling of commercial refrigeration cycles.
- Safety Compliance: Acts as a critical limit control to prevent compressor damage and potential safety hazards from over-pressurization.
Common Questions
Is this a manual or automatic reset switch?
This high pressure switch typically functions as an automatic reset component, closing the circuit once the system pressure drops back to the 185 PSI cut-in point.
What causes this switch to trip in a standard HVAC system?
Common triggers include a dirty condenser coil, a failed condenser fan motor, or an overcharge of refrigerant, all of which lead to high discharge pressures.
Can I use this switch for low-pressure applications?
No, the 290/185# rating is specifically calibrated for high-side protection. Using it on the suction side will prevent the compressor from operating under standard evaporator pressures.
Item is Non Cancelable / Non Returnable
