Description
The Trane SWT3197 is an OEM low pressure switch engineered to protect refrigerant circuits in Trane HVAC systems. Designed with precise open and close setpoints, this switch automatically interrupts system operation when refrigerant pressure drops to unsafe levels, helping prevent compressor damage and costly repairs.
How It Works
The SWT3197 monitors refrigerant-side pressure continuously. When system pressure falls to the open setpoint, the switch opens the control circuit, shutting down the compressor. Once pressure recovers to the close setpoint, the circuit is restored and normal operation resumes.
