摘要： Provided are a fuse and a circuit system. The fuse includes: a housing, a closed chamber being provided in the housing and being filled with an arc extinguishing filler, and a first conductive terminal and a second conductive terminal which are used as a current input end and a current output end being respectively connected to the housing; a melt which is connected in series between the first conductive terminal and the second conductive terminal, at least part of the melt being disposed through the closed chamber; and an impact apparatus, which is arranged in the housing, is positioned outside the closed chamber, and is configured to act, when receiving an excitation signal, on the melt to generate an impact force to make the melt break in the closed chamber.
