The Trane SWT03739 is an OEM high pressure switch engineered to protect refrigeration circuits and compressors from dangerous over-pressure conditions. Designed as a direct Trane replacement component, this switch provides dependable, automatic pressure-based protection for commercial and residential HVAC systems.
How It Works
The SWT03739 monitors system refrigerant pressure continuously. When high-side pressure reaches the open setpoint, the switch interrupts the circuit to prevent compressor or system damage. Once pressure drops back to the close setpoint, the switch resets and allows normal operation to resume.
