Trane SWT03698 Pressure Switch 650# Open / 500# Close

Description

The Trane SWT03698 is an OEM pressure switch engineered to protect HVAC refrigeration circuits by monitoring system pressure and interrupting operation when unsafe conditions are detected. With a precisely calibrated open setpoint of 650 psi and a close setpoint of 500 psi, this switch provides a reliable 150 psi differential to prevent nuisance tripping while still safeguarding compressors and associated components from high-pressure damage.

Key Features

• Open (trip) setpoint: 650 psi
• Close (reset) setpoint: 500 psi
• 150 psi operating differential for stable, reliable switching
• OEM Trane replacement part — direct-fit for compatible Trane equipment
• Designed to protect compressors and refrigeration circuits from high-pressure conditions
• Durable construction for long service life in demanding HVAC applications

Application

The SWT03698 is a factory-authorized Trane replacement pressure switch intended for use in commercial and residential HVAC systems. It monitors refrigerant-side pressure and opens the control circuit when pressure exceeds the 650 psi threshold, shutting down the system to prevent equipment damage. The circuit automatically resets once pressure drops to the 500 psi close setpoint, restoring normal operation.
