**THERMAL OVERLOAD PROTECTION SYSTEM: (Controller and Heater protection system must match)
Protector 1 (P1)-Standard over-temperature control system utilizes a heat sensitive fuse to detect overheat conditions. The fuse, placed inside a thermowell, positioned in contact with the heater sheath, will cut power to the heater in the event of low liquid level.
Protector 2 (P2) and Protector 3 (P3) -Optional systems provide the same reliable over temperature protection as the Protector 1; 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, 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. Protector III is designed for flexible lead or high temperature fluoropolymer (PTFE) heater applications only. DO NOT wire P3 or PT-3 devices directly to power or heater load as a dangerous short circuit will result with irreparable damage to the heater. Please refer to wiring diagrams for proper installation.
Guards recommended for all fluoropolymer and quartz heaters. Standard guard is polypropylene. Special fluoropolymer (PTFE) guards for chromic acid solutions exceeding 180°F (82°C) available (contact us)
