Protector 1, 2 and 3 Series

Thermal Overload Protection comes standard on all traditional style Process Technology over-the-side and bottom (L-shaped) industrial immersion heaters. Please check that these devices are properly installed to ensure safe operation of the heaters.

Features:

The Protector 1 Series

The Protector 1 overtemperature control system utilizes a heat sensitive protector 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 level.

The Protector 2 and 3 Series
The Protector 2 and Protector 3 systems provide the same reliable overtemperature 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 3 is designed for flexible lead or high temperature fluoropolymer (PTFE) heater applications only. DO NOT wire P3 or P8 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.

Order replacement protectors by item number (below). P3 option not available on 8 and 9 kW elements. Lowest temperature replaceable style Protector standard unless otherwise designated.
