Carrier HK02ZA402 Pressure Switch
The Carrier HK02ZA402 is a high-performance manual reset pressure switch designed specifically for HVAC systems requiring critical safety cut-out protection. This SPST high pressure switch is factory-calibrated to open at 610 PSI and close at 420 PSI, ensuring the compressor is shielded from extreme head pressure conditions that can lead to catastrophic mechanical failure. Engineered for seamless integration with Carrier, Bryant, and Payne condensing units, this component features a 1/4 inch SAE female flare fitting for a secure, leak-proof connection to the liquid line or discharge service valve. Replacing a failed HK02ZA402 high pressure switch is essential for maintaining system integrity and meeting OEM operational standards. Its robust construction resists vibration and internal pressure spikes, providing reliable HVAC safety switch performance in demanding commercial and residential environments. Ensure system pressures are stabilized before manual reset to prevent repeated tripping and potential contact fatigue.
Key Benefits for Contractors
- Precise Trip Point: Calibrated to trigger at 610 PSI, preventing damage from refrigerant overcharge or condenser fan failure.
- OEM Compatibility: Exact drop-in replacement for specific Carrier and Bryant models, eliminating the need for field modifications.
- Reliable SPST Logic: Simple single-pole, single-throw configuration integrates easily into the existing 24V or 120V safety circuit.
- Durable Construction: Built to withstand high-cycle rates and harsh environmental exposure typical of outdoor units.
Common Installation Questions
What is the reset logic on the HK02ZA402?
This is a manual reset switch. If the pressure exceeds 610 PSI, the circuit opens and must be manually bypassed or depressed to close once pressure drops below 420 PSI.
Can this switch be used in R-410A systems?
Yes, the 610/420 PSI range is specifically engineered for the higher operating pressures of R-410A refrigerant safety protocols.
Does this part include the wiring harness?
This SKU typicaly utilizes the existing lead wires or standard spade terminals; verify your specific unit's terminal configuration during replacement.
Item is Non Cancelable / Non Returnable
