Supco SHM350 Manual Reset Thermostat 350°F

The Supco SHM350 Open Thermostat is a high-temperature control that is installed in HVAC systems to interrupt a circuit when the temperatures inside the system rise to an unsafe level. It works by closing its contacts when 350°F is reached, and it has to be manually reset to resume its operation. Installation is the procedure of fitting the thermostat in the suitable heat-sensitive section of the system and connecting it to the control wiring as per specifications. This is a manual reset thermostat that overheats by turning off.
