Thermal Fuses (also named thermal cut out or TCO)

Thermal fuses open the circuit if the heater exceeds the selected fuse temperature. They are a one time over temperature protection device that can prevent heater runaway in the event of a control device failure.

  • Testing must be made to select the best location and temperature setting of the fuse upon application.
  • Fuses are preset with a range of 150 oF to 460 oF. Electrical ratings are 120/250 VAC and 15 amp maximum

As the TCO body is electrically live, they must be covered by a silicone rubber/fiberglass foil or boot vulcanized or bonded to the heater body
