Thermal overload protection

The Protector 1 overtemperature control system utilizes a heat sensitive fuse to detect overheat conditions. The protector, placed inside a thermowell, positioned in contact with the heater sheath, will cut power to the heater in the event of low liquid.

The Protector 2 and Protector 3 systems provide the same reliable overtemperature protection as Protector 1; however, the control systems feature a heat-sensing thermostat. If the liquid level drops and the heater reaches a preset overheat heater can quickly be made operational by pushing the reset button on the control to restore power.

Protector 3 is designed for flexible lead or high-temperature fluoropolymer (PTFE) heater applications only.
