This research discusses the NV melting fuse, which is used to protect various types of circuits because of its good properties. The calculation is based on the 3D finite element (FE) analysis that is conducted with the software Vector Fields Opera. Current field analysis has been conducted from which Joule losses are determined along with static and transient analysis of thermal field of NV melting fuse. Analyses have been carried out for a different melting fuse current and for different shape of perforation of melting fuse. The obtained results provide necessary information on distribution of Joule losses and temperatures for cases of different currents.
