Supco SLP2550 Low Pressure Control Switch with Automatic Reset

The Supco SLP2550 is a low pressure control switch designed for refrigeration and air conditioning systems. This automatic reset control is engineered to open on pressure fall, providing critical system protection by shutting down the compressor when refrigerant pressure drops below safe operating levels.

Key Specifications:

• Cut-out pressure: 25 PSI (opens when pressure falls to this level)
• Cut-in pressure: 50 PSI (closes when pressure rises to this level)
• Automatic reset operation for convenient system restart
• Designed for sealed refrigeration units and HVAC applications
• Protects compressor from low refrigerant charge and loss of charge conditions

This pressure control helps prevent compressor damage due to insufficient lubrication or refrigerant flow. The automatic reset feature allows the system to resume normal operation once pressure is restored to safe levels, eliminating the need for manual intervention. Ideal for use in commercial refrigeration, air conditioning systems, and other sealed unit applications where reliable low-side pressure monitoring is essential.
