Thermal Fuses

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 that a control device has frozen in the on position. Testing is suggested to select the location and temperature setting of the fuse to protect your product most effectively. 

Fuses are preset with a range of 150°F to 460°F. Electrical ratings are 120/250 VAC and 15 amp maximum. They must be covered or enclosed because the outer case of the fuse is electrically live.
