Supco SHP480380 High Pressure Switch 480 PSI Open 380 PSI Close

The Supco SHP480380 is a high-pressure switch designed for HVAC and refrigeration systems, engineered to open on pressure rise at 480 PSI and close at 380 PSI. This automatic reset pressure control provides reliable monitoring and protection for air conditioning units, refrigeration equipment, and other pressure-sensitive applications.

Key Features:

• Opens at 480 PSI, closes at 380 PSI with ±15 PSI tolerance
• Single pole, single throw (SPST) configuration opens on pressure rise
• Rated for 24/120/240 VAC at 50/60 Hz
• Automatic reset for continuous operation
• Snap-acting stainless steel hermetically sealed sensor
• 1/4" SAE 45° female flare fitting with valve core depressor
• Compact design for direct mounting applications
• 18 AWG wire leads, 18" long
• Working pressure range: 0 to 650 PSI, bursting pressure: 5,000 PSI
• Operating temperature range: -31°F to 248°F (-35°C to 120°C)
• 100,000 cycle life at rated load

This pressure switch features excellent set point repeatability and stability, making it ideal for fan cycling controls, compressor protection, and general pressure monitoring in commercial and industrial HVAC/R systems. Its small size and lightweight construction allow for convenient installation directly on refrigeration lines and pressure vessels.
