What is a Resettable Fuse?
A resettable fuse, also known as a PPTC or polymeric positive temperature coefficient fuse, is a fuse that trips when the flow of current received is more than the amount that can be managed by the device or wiring. This helps in preventing damage to the attached equipment. A resettable fuse has the advantage of being able to reset itself once the power overload is reversed and current flow is restored to a normal range.
