Description
The Trane CNT07731 High Pressure Switch is a refrigerant pressure monitoring component used within cooling and refrigeration system to supervise discharge-side operating conditions in HVAC systems. Configured with 650 PSI open, and 550 PSI reset pressure thresholds it responds to elevated refrigerant pressure levels by changing circuit status when predetermined limits are reached. The switch is commonly used into condensing units, rooftop part, and refrigeration assemblies where pressure-sensitive control operates are required. Connected to safety circuits and control wiring, it works as a pressure-responsive protection element that communicates pressure conditions to associated control equipment.
