Supco High Pressure Switch HVAC Refrigeration

The Supco High Pressure Switch is a fixed-setpoint, automatic-reset pressure control for HVAC and refrigeration systems. It is also called a high pressure cutout or high pressure control. It opens the control circuit when system pressure rises, which helps protect compressors and other components from excessive head pressure. Typical causes include a dirty condenser coil, a condenser fan failure, or a refrigerant overcharge.

Key Features:

• Opens on pressure rise and recloses automatically when pressure drops to its close point
• Encapsulated, non-adjustable, single-pole single-throw (SPST) direct-mount design
• Suitable for use with HFC, HCFC and CFC refrigerants
• 1/4" SAE 45° female flare fitting with valve core depressor
• Snap-acting, hermetically sealed stainless steel sensor
• Rated for 24/120/240 VAC at 50/60 Hz
• Rated life of 100,000 cycles at rated load
• 18 AWG, 18" long lead wires
• Small, lightweight body for direct mounting
• Good set point repeatability and stability
• UL Recognized

Applications: Air conditioning, heat pump and refrigeration systems, as a replacement or add-on safety cutout. Match the open and close pressure settings to the equipment manufacturer's requirements. Each part number in this line has its own open and close pressure rating.
