Description
The Trane SWT3403 is a high-pressure safety switch engineered to protect refrigerant circuits from damaging over-pressure conditions. Designed as a genuine Trane OEM replacement component, this switch delivers dependable, automatic pressure monitoring to safeguard compressors and refrigeration systems against high-side pressure faults.
How It Works
The SWT3403 monitors high-side refrigerant pressure and interrupts the circuit when pressure reaches the open setpoint, preventing compressor damage and system failures. Once pressure drops to the close setpoint, the switch resets to restore normal operation.
