Description
The Trane SWT01280 Thermal Limit Switch is a temperature-actuated safety control component used to monitor operating conditions in heating and air handling equipment. It responds to thermal rise by opening the electrical circuit at 155F and reclosing at 125F, providing automatic protection and reset capability. It is applied in furnace and air distribution HVAC systems where controlled shutdown is required to prevent overheating. Within the control assembly, it supports equipment protection, regulates safe operating boundaries, and helps maintain system performance during normal operation, recovery cycles, and abnormal heat conditions.
