Description
The Trane CNT7660 L120-30°F Limit Switch is a safety component in many Trane HVAC systems. It protects equipment from freezing and damaging equipment from dangerously low temperatures. This limit switch has a temperature sensor that is continuously tracking the temperature. If the temperature goes below 30°F, the device will automatically open the circuit to prevent the equipment from running at dangerously low temperatures cut in the range of 120–30°F. Once the temperature is safe again, the switch immediately resets and allows the device to work again.
