Trane THT3044 CO Limit Switch Manual Reset 200°F

The Trane THT3044 manual reset limit switch is installed in the HVAC systems to avoid excessive heat build-up. It is designed to open at 200°F to stop power to the equipment to prevent damage. This switch is usually used to safeguard important parts such as compressors and motors. If the temperature goes beyond the set point, the switch is turned off, which stops the power supply. The strength of this design is that the switch has the capability of manual reset where the user is required to reset the switch after the condition of overheating has been solved.
