DF-Series
Thermal Cutoffs are designed to provide upper limit temperature protection for all the electric and electronic products, keeping the products functioning properly and safely and then protecting lives and property as well as products from possible fires. Usage: Refrigerators, Washing Machines, Electric Irons, etc
Note: There are two major sources of heat to operate the fuse.
(1) External heat transferred from outside the periphery of the fuse
(2) Self-heating by conductivity
