What does a "self-resetting" fuse do?

A "self-resetting" fuse is designed to automatically restore the circuit once the fault that caused it to trip has been cleared. This type of fuse uses materials that can withstand temporary overload conditions. When an overload occurs, the fuse heats up and interrupts the circuit, but once the overload condition is removed, the internal mechanism cools down enough to allow the connection to be re-established without requiring any manual intervention.

This functionality is particularly advantageous in applications where it is not feasible for users to routinely check and reset fuses, such as in remote or hard-to-access locations. By automatically resetting, it enhances convenience and reduces downtime, allowing devices to continue operating without the need for manual resets.
