Carrier HH12ZB180 3" Auto Limit Switch 180°F

The Carrier HH12ZB180 3" Auto Limit Switch 180°F maintains a temperature detector that is integrated into the HVAC systems to regulate and check on the amount of heat. It has a sensing component that has been too close or open within the range to enable automatic shutoff when temperatures are higher than the preset limits. It is directly attached to the heat exchange or duct section to be alerted to high temperatures. It stops electrical currents when heating components get hot to protect and aid in operation to ensure steady performance in furnaces, boilers, and other gas-fired equipment.
