WebA backup current-limiting fuse as defined by IEEE Std C37.40™– 2003 standard is a fuse capable of interrupting all currents from the rated interrupting current down to the rated minimum interrupting current, which means that the fuse must be paired with a low current series device in order to achieve full-range protection. Two examples Webfuse blowup during inrush current events. In addition, once the fuse blows during an overload event, it has to be physically replaced, which increases system down time and maintenance costs. On the other hand, PTC resistors provide resettable overcurrent protection and, unlike a fuse, these can avoid the physical
