Description
The Trane SWT03629 is an OEM high pressure switch engineered to protect refrigeration and HVAC systems from dangerous over-pressure conditions. Designed as a direct factory replacement for compatible Trane equipment, this switch monitors system refrigerant pressure and automatically interrupts the circuit when pressure reaches unsafe levels, then resets as pressure returns to a safe operating range.
How It Works
The SWT03629 is a normally closed pressure switch that opens its electrical contacts when system pressure rises to the trip point, cutting power to the compressor or control circuit to prevent equipment damage. Once system pressure drops back to the reset threshold, the switch closes and allows normal operation to resume.
Pressure Specifications
- Opens (trips) at: 400 PSI
- Closes (resets) at: 250 PSI
Key Features
- Genuine Trane OEM replacement part
- High-pressure safety switch for refrigeration and HVAC systems
- Automatic reset design — closes at 250 PSI after pressure subsides
- Protects compressors and system components from over-pressure damage
- Direct drop-in replacement for compatible Trane equipment
Application
The SWT03629 is intended for use in Trane commercial and residential HVAC and refrigeration systems where high-side pressure protection is required. Always verify compatibility with your specific Trane unit model before installation. Consult the equipment service manual for wiring and mounting instructions.
