Carrier HH12HA142 Limit Switch 140°F Manual Reset

The Carrier HH12HA142 Limit Switch is an essential safety device developed to be used in HVAC systems. It has a manual reset button and the machine is set to work at 140°F. This limit switch is applied in furnaces and heating equipment where the operation of the system is interlocked in such a way that it stops working when it overheats. The manual reset function makes it even safer because once the switch has been activated, it has to be reset by hand to work again. Advantages of using this switch include better protection against overheating, better safety for HVAC systems as well as safety standards.
