Description
The AAON G151230 is a high-pressure safety switch engineered for R-22 refrigerant systems, providing reliable over-pressure protection in commercial HVAC applications. Rated at 450 PSI, this switch is designed to shut down the system when refrigerant pressure exceeds safe operating limits, helping to prevent compressor damage and costly equipment failures.
Key Features
- 450 PSI (450#) high-pressure rating for robust system protection
- Manual reset (M/R) design ensures intentional operator acknowledgment before system restart
- Engineered for use with R-22 refrigerant systems
- OEM AAON replacement part — direct fit for compatible AAON equipment
- Helps safeguard compressors and refrigerant circuits from damaging over-pressure conditions
Application
This high-pressure switch is an OEM-grade replacement component intended for AAON commercial rooftop units and air conditioning systems that utilize R-22 refrigerant. The manual reset function requires a technician to physically reset the switch after a high-pressure trip event, ensuring the root cause is identified and addressed before the system is returned to operation.
Why Manual Reset Matters
Unlike automatic reset switches, a manual reset high-pressure switch prevents the system from cycling back on repeatedly after a fault condition. This added layer of protection reduces the risk of compressor failure, refrigerant leaks, and unplanned downtime — making it the preferred choice for commercial and industrial HVAC installations.
