Which type of fuse melts several sections of the link in a short circuit condition?

A dual element fuse is designed to offer enhanced protection in electrical circuits by incorporating two separate elements. When a short circuit occurs, the current surges rapidly, leading the dual element fuse to respond by melting one or more of these elements, effectively interrupting the circuit. This design allows the fuse to handle temporary overload conditions better than single element fuses, while still providing protection against sustained overloads and short circuits.

In contrast, a single element fuse typically has only one fusible link, which would melt under excessive current but does not provide the same level of dual-layer protection. Other types of fuses, such as slow blow and fast blow fuses, are designed based on the speed of response to overload or short circuit conditions, but they do not have multiple elements, and therefore would not melt multiple sections of a link as part of their current interruption process.
