Supco High Pressure Switch

The Supco High Pressure Switch line is a family of refrigeration and HVAC high pressure cutout switches. Each one opens its circuit when pressure rises and closes again once pressure falls back to its reset point. Technicians use them as a safety control, also called a high pressure control or high pressure cutout, in air conditioning, heat pump and refrigeration systems. They protect compressors and other components from excessive discharge pressure.

Key Features:

• Opens on pressure rise, with automatic reset
• Snap-acting, hermetically sealed stainless steel sensor
• 1/4 inch SAE 45 degree female flare fitting with valve core depressor for direct mounting
• Compatible with all refrigerants, including the newer A2L refrigerants
• Rated for 24/120/240 VAC at 50/60 Hz
• Life of 100,000 cycles at rated load
• Burst pressure of 5,000 PSI
• Pre-wired with 18 AWG, 18 inch leads
• UL Recognized and CE certified

These switches are compact and lightweight, so they are easy to install and fit into tight spaces. They give repeatable, stable set points. Supco is a long-time supplier of HVAC/R replacement parts and controls. Each switch in the line has its own factory-fixed open and close pressure settings, so you can match the control to the equipment.
