Carrier HH18HA291 Manual Reset Limit Switch 290°F

The Carrier HH18HA291 Limit Switch is an essential safety device that is used in HVAC systems, especially in heating appliances and furnaces. This M/R limit switch works at a cutoff temperature of 290°F and thus prevents the system from overheating, which in turn may cause harm or loss. This switch blows the electrical fuse when the temperature is too high and the circuit has to be manually reset, this is a safety feature since it ensures that any problem is sorted out before the system is switched on again.
