Resettable fuses also known as polymeric positive temperature coefficient (PPTC) fuses, are essential components in the Fuse category. These fuses automatically restore conductivity after tripping, providing reliable protection for electronic circuits.
Ideal for applications requiring frequent overcurrent protection, resettable fuses prevent damage by limiting excessive current flow. Once the fault is cleared, they cool down and reset, ready to protect again without needing replacement. Commonly used in consumer electronics, automotive systems, and industrial equipment, resettable fuses enhance safety and reduce downtime.
