There is a chart toward the bottom of this web page that gives a decent overview of the different fuse classes, including the Class T.

If what you want are the specific details of a particular Class T fuse, then it's best to pick a specific manufacturer and download THEIR fuse curves for that fuse. the UL standards include a "range" of acceptability, one mfr may not be exactly the same as another.

Type "T"; do you mean like UK type "T"https://uk.rs-online.com/web/p/bolted-tag-fuses/0415222/or USA Class T??

When you say power distribution line, you are referring to Drop-out (DO) or Expulsion type fuses I guess. Bussmann has a catalog, giving details including K-type and T-type fuse curves. In simple terms, K-type are called Fast-blow type and T-type, the Slow-blow type.

Thanks a lot . i was actually searching for that info .you make my way much simple with few words.
