A PTC (positive temperature coefficient) re-settable fuse works by using a polymer material that has a high resistance at normal operating temperatures. When a high current or overcurrent condition occurs, the PTC fuse heats up and its resistance increases dramatically, effectively limiting the current flow and protecting the circuit. Once the overcurrent condition is removed, the PTC fuse cools down and its resistance decreases, allowing the circuit to function normally again. This self-resetting feature makes PTC fuses ideal for protecting electronic circuits from overcurrent events. **
