THERMAL OVERLOAD PROTECTION PROTECTOR I SERIES (Standard on all electric immersion heaters) The Protector I over-temperature control system utilizes a heat sensitive fuse to detect overheating conditions. The fuse, placed inside a thermowell, positioned in contact with the heater sheath, will cut power to the heater in the event of a low liquid level.
PROTECTOR II AND PROTECTOR III SERIES (Optional - Consult Sales Dept.) The Protector II and Protector III systems provide the same reliable over-temperature protection as the Protector I; however, the control systems feature a heat sensing thermostat. Should the tank's liquid level drop to a preset overheat point, the thermostat will trip and an audible alarm will sound, as well as cutting power to the heater. This eliminates dangerous operating conditions. After filling the tank, the immersion heater can be quickly made operational by pushing the reset button on the control to restore power.
