Description
The Trane CNT3086 Low Pressure Switch operates as a vital safety element in HVAC systems for refrigerant pressure detection. This protective component operates based on pressure differences between points. This system safety system activates at 30 PSI operation pressure yet 40 PSI close pressure to open the circuit and stop system operation when the pressure drops below 30 PSI. The system protects compressors from running when refrigerant pressure drops too low because such conditions might cause equipment damage. The system continues normal operation after the pressure reaches 40 PSI and triggers the switch to close. The Trane HVAC equipment lineup consisting of air conditioners and heat pumps uses that as their primary component.
