Description
The Trane SWT01720 High Pressure Switch is an safety control designed to protect refrigeration system from excessive discharge or head pressure in HVAC systems. It is installed in the refrigerant circuit of compatible air conditioning and heat pump equipment, where it monitors pressure conditions and interfaces with the control circuit. The switch is calibrated to open at 405 PSI and reset close at 300 PSI, interrupting the control signal if pressure exceeds safe operating limits. As part of the systems protection and control assembly it works alongside components such as the compressor, condenser fan.
