Description
The Lennox 10U65 Normally Closed High Pressure Switch is a pressure safety control used in refrigeration circuits to monitor refrigerant pressure within the system. It is placed on the high-pressure side of air conditioning or heat pump equipment where it responds to excessive pressure conditions within HVAC systems. The switch opens at 640 PSI and resets at 475 PSI, interrupting the control circuit to stop compressor operation when unsafe pressure levels are detected. This component is commonly used in Lennox systems, supporting compressor protection, maintaining operating limits and assisting better system shutdown during abnormal pressure conditions.
