Description
Trane SWT1156 Manual Reset High Pressure Switch
The Trane SWT1156 is a manual reset (M/R) high pressure switch engineered to safeguard refrigeration and HVAC systems against unsafe high-side pressure conditions. Designed as a direct OEM replacement for compatible Trane equipment, this switch provides reliable system protection by interrupting the circuit when pressure exceeds the set point — requiring a deliberate manual reset before the system can resume operation. This built-in safety feature helps technicians identify and address the root cause of over-pressurization before restarting, reducing the risk of equipment damage and costly repairs.
Key Features
- Manual reset (M/R) operation — prevents automatic restart after a high-pressure trip event
- 37″ lead wires for flexible installation and routing in tight equipment spaces
- OEM Trane replacement part for precise fit and reliable performance
- Protects compressors and refrigerant circuits from damaging over-pressurization
- Durable construction built to withstand the demands of commercial and residential HVAC applications
Application
The SWT1156 is intended for use in Trane HVAC and refrigeration systems requiring high-side pressure protection. The manual reset design is ideal for applications where automatic restart after a fault condition is undesirable, ensuring a qualified technician evaluates the system before it is returned to service. The 37″ leads provide ample length for convenient wiring in a variety of installation configurations.
