Supco SHP610420 High Pressure Switch 610 PSI Close 420 PSI Open

The Supco SHP610420 is a genuine OEM high-pressure switch designed for HVAC and refrigeration systems. This pressure-actuated safety control is engineered to protect compressors and system components from damage caused by excessive refrigerant pressure.

Key Specifications:

• Cut-out (close) pressure: 610 PSI
• Cut-in (open) pressure: 420 PSI
• Automatic reset high-pressure switch design
• Suitable for air conditioning and refrigeration applications
• Direct replacement for original equipment manufacturer parts

This pressure switch monitors refrigerant pressure on the high side of the system. When pressure exceeds 610 PSI, the switch opens the circuit to shut down the compressor. Once pressure drops to 420 PSI, the switch automatically resets and closes the circuit, allowing normal operation to resume. The automatic reset feature eliminates the need for manual intervention during temporary pressure spikes.
