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。
Selection of fuses must be carried out according to their use conditions, mainly they are system voltage, rated current, short circuit capacity, protection suitability etc.
在电路设计工作中，很大一部分工作是在验证熔断器与线型选择是否合理、是否匹配。
Most of the work in circuitry design is verifying whether the selection of fuse and wire is reasonable and matching.
熔断器的熔断特性曲线如图1，供选择熔断器时参考。
Refer to its fusing feature curve in chart 1 when select the fuse.
