Supco SHP300200 High Pressure Switch 300 Open PSI (CUT-OUT) 200 Close PSI (CUT-IN)

The Supco SHP300200 High Pressure Switch is a component that is used to check and control the refrigeration and HVAC systems. It is closed at 300 PSI to prevent overpressure, and it is opened at 200 PSI to allow normal operation. It is mounted on the high-pressure side of compressors or refrigeration circuits to avoid damaging valuable components of the circuit, such as compressors, valves, and piping as a result of high pressure. Being a safe and control element, the switch ensures the stable operation of the system and supports the refrigeration and HVAC equipment.
