Aaon G151230 R22 High Pressure Switch 450 PSI Manual Reset

The Aaon G151230 is a high-pressure safety switch designed for R22 refrigerant systems, rated for 450 PSI cutout pressure. This manual reset switch provides critical over-pressure protection for commercial HVAC equipment, automatically shutting down the system when discharge pressure exceeds safe operating limits.

Key Features:

• 450 PSI pressure cutout rating for R22 refrigerant applications
• Manual reset functionality requires technician intervention after trip event
• Designed specifically for Aaon rooftop units and HVAC equipment
• Protects compressor and system components from damaging high-pressure conditions
• Direct OEM replacement part ensuring proper fit and function

This high-pressure switch is a critical safety component that monitors refrigerant discharge pressure on the high side of the system. When pressure exceeds the 450 PSI threshold, the switch opens the control circuit to shut down the compressor. The manual reset design ensures that a qualified technician must diagnose and correct the underlying cause before the system can be restarted, preventing repeated nuisance trips and potential equipment damage.
