Low-Pressure SPST Refrigerant Pressure Switch, 5 PSI Open / 30 PSI Close

This low-pressure refrigerant pressure switch is for HVAC and refrigeration technicians who need to monitor pressure in systems using HFC, HCFC, or CFC refrigerants. It opens on a pressure fall at 5 PSI and closes at 30 PSI to support pressure-based system control.

The encapsulated, non-adjustable single-pole, single-throw switch is designed for direct mounting. It has an SAE female flare fitting with a valve core depressor and a snap-acting, hermetically sealed stainless steel sensor. Rated for 24, 120, or 240 volts at 50/60 Hz, it has a 0 to 650 PSI pressure range, 5,000 PSI burst pressure, and a rated-load life of 100,000 cycles. Overall dimensions are 3.5 x 5 x 1.5 inches.

Key Features:

• 5 PSI open point: Opens the circuit when pressure falls to 5 PSI for low-pressure control.
• 30 PSI close point: Closes the circuit at 30 PSI for a defined pressure reset point.
• Non-adjustable SPST design: Provides a fixed pressure switching function without field adjustment.
• Direct-mount fitting: The SAE female flare connection with valve core depressor supports direct installation.
• Sealed stainless steel sensor: Hermetically sealed, snap-acting sensor construction supports consistent switching performance.

Choose this fixed-setting pressure switch for compatible refrigerant systems that require low-pressure opening at 5 PSI and closing at 30 PSI.
