This element is of proper shape and cross-section to carry ratedcurrent continuously and to melt in accordance with a specific time-current characteristic on heavy overload or shortcircuit.
Selection of fuses must be carried out according to their use conditions, mainly they are system voltage, ratedcurrent, shortcircuit capacity, protection suitability etc.
熔断器选择必须依据其使用条件来进行，主要有系统电压、额定电流、短路容量、保护配合等。

The shortcircuitcurrent calculation shows the rated thermal stability current of former current mutual inductor is too small.
