Aaon G151220 High Pressure Switch 600 PSI Manual Reset

The Aaon G151220 is a genuine OEM high-pressure safety switch rated at 600 PSI with a manual reset function, designed for use in commercial HVAC refrigeration systems. This switch monitors refrigerant discharge pressure on the high side of the system and protects compressors and system components from damaging over-pressure conditions.

When refrigerant pressure exceeds the 600 PSI cutout threshold, the switch opens the control circuit to shut down the compressor. The manual reset design requires a qualified technician to diagnose and correct the underlying cause before the system can be restarted, preventing repeated nuisance trips and potential equipment damage.

Key Features:

• 600 PSI cutout pressure rating
• Manual reset (M/R) — requires technician intervention after a trip event
• Genuine OEM Aaon replacement part — ensures proper fit and reliable performance
• Designed for integration with Aaon commercial HVAC equipment
• Compatible with Aaon rooftop units, split systems, air handlers, and heat pumps
• Part of the Aaon G151xxx high-pressure switch series

This is a direct OEM replacement part. Always use genuine Aaon parts to ensure safety, reliability, and optimal system performance.
