Fenwal 11-030000-000 Openrise Thermoswitch 50°F-300°F

The Fenwal 11-030000-000 Openrise Thermoswitch is used to check the thermal conditions in HVAC systems. Its main operation is to interrupt the electrical circuit once the temperature is sensed at any level within the range of 50°F to 300°F above the set point. The mechanism of operation of the switch is an internal mechanism that reacts to the change of heat at the point of sensing and opens the contact. It is installed by placing it in the specified area of exposure to temperature and connecting the electrical system as per specifications.
