Melt capable of realizing low-current breaking and pressing method thereof

The invention relates to a melt capable of realizing low-current breaking and a pressing method thereof, the melt is provided with first variable cross sections which are formed by narrow diameters in the length direction of the melt, and an arc isolation belt and a second variable cross section are arranged between two adjacent first variable cross sections on the melt. The second variable cross section is longer than the first variable cross section; on the basis, the multiple melts forming the second variable cross section in the width direction of the whole melt are not located on the same plane, one of the adjacent melts protrudes upwards, the other one of the adjacent melts sinks downwards, a three-dimensional structure is formed, when a system has a low overload fault and small current needs to be divided, the arc crossing phenomenon after arcing is avoided, and the service life of the system is prolonged. And moreover, because of the long strip shape, the arcing zone is relatively long, the effect of
