Supco Low Pressure Switch

The Supco Low Pressure Switch is a refrigerant low-pressure control for HVAC and refrigeration systems. It is also called a low pressure cutout switch or refrigeration pressure control. It monitors system pressure on the low side and opens the control circuit if pressure drops below a set point. This helps protect compressors and other components from damage caused by low refrigerant charge, loss of airflow, or other low-pressure conditions.

Key Features:

• Automatically opens and closes the electrical circuit at preset pressure points
• Helps protect compressors from running under low-pressure conditions
• Designed for HVAC and refrigeration applications
• Available with different open and close pressure settings to suit different system requirements
• Automatic reset operation lets the system restart once pressure recovers
