Abstract:
A flat spring (100) is disclosed, for use in a surge protection device (SPD) such as a fast activation thermal fuse, to be integrated with a thermal metal oxide varistor (TMOV). The flat spring (100) has a V-shaped protrusion (110) to enable ultra-high short circuit current protection under overvoltage condition.
