Ranco O10-1402 Pressure Control Switch 12"WC-50 PSI Cut-Out 35 PSI Cut-In

The Ranco O10-1402 is a single-pole single-throw (SPST) pressure control switch designed for HVAC and refrigeration applications. This automatic pressure control opens on low pressure, providing reliable system protection and operation control.

Key Specifications:

• Pressure range: 12 inches water column to 50 PSI
• Cut-out pressure: 50 PSI (opens circuit on low pressure)
• Cut-in pressure: 35 PSI (closes circuit when pressure rises)
• Capillary length: 36 inches
• Contact configuration: SPST (single pole, single throw) normally open on low pressure
• Suitable for refrigeration and air conditioning pressure control applications

This pressure control switch is commonly used to monitor and control system pressure in commercial refrigeration units, air conditioning systems, and other HVAC equipment. The extended 36-inch capillary tube allows flexible mounting and remote sensing capabilities. When system pressure drops to the cut-out point, the switch opens to protect the compressor or other equipment from low-pressure damage.
