Description
The Trane SWT03940 Thermal Switch Open 145F Close 115F is a temperature-sensitive control component designed for heating and cooling equipment in HVAC systems. It operates by responding to temperature conditions, opening its electrical circuit. It has a 145F and closes again when the temperature drops to 115F, allowing for controlled cycling of connected components. It is placed in air handlers, furnaces, and ventilation assemblies, and it regulates equipment operation based on thermal conditions to prevent overheating and maintain proper system operation. It supports proper and efficient operation by assisting in temperature-based control of fans, motors, and electrical components.
