fuse的溶斷問題

Fuse有分快斷, 和慢斷, 有什麼實際作用呢?
快斷 = Fast Blow 用於較敏感既儀器
慢斷 = Slow Blow 用於需要啓動電流既儀器
什麼是 breaking capacity?
breaking capacity 短路容量

The breaking capacity gives the current that a fuse is able to interrupt without being destroyed or causing an electric arc. The maximum short circuit current which can occur under fault conditions should not exceed the rated breaking capacity of the fuse. Otherwise a safe protection of the device cannot be guaranteed.
