The Aaon G024540 is a factory-specified high pressure switch designed as a direct OEM replacement for Aaon commercial HVAC equipment. Engineered to protect refrigerant circuits from dangerous overpressure conditions, this switch monitors system pressure and interrupts operation when limits are exceeded — safeguarding compressors, coils, and associated components from damage.
Overview
This high pressure switch features a 475 lb cut-out (trip) pressure and a 650 lb cut-in (reset) pressure, making it well-suited for high-side refrigerant circuit protection in Aaon rooftop units and other commercial systems. Using an OEM-matched replacement like the G024540 ensures proper calibration, reliable operation, and compatibility with existing controls and wiring.
