ELCUT Thermal Cutoffs are available with axial or radial lead wires, both having the same basic design. The fusible thermal element is a fusible alloy that is welded across a pair of lead wires. The fusible alloy is coated with a special compound to ensure stable and reliable fusing off of the thermal element. The coated element is sealed in a special insulated container housing. The final product is a miniaturized, fusible alloy-type thermal unit with extremely simple construction
When the cutoff temperature is reached, the thermal element melts and liquefies. This breaks or “cuts-off” the electrical current through the thermal fuse.
