Self-recovering fuses are the next-generation overcurrent protection products, functionally equivalent to automatic-resettable and reusable fuses. They are used to protect circuits from damage due to excessive current in electrical circuits, featuring automatic reset, high safety, short reset time, excellent resistance to high currents, and compact size.

Suitable for use in communication switches, main distribution frames, computer mice, keyboards, miniature motors, transformers, speakers, batteries (sets), and other electrical equipment and circuits, serving as an overload protection function.
