All, Over the years, I've seen various ways people include a caution or warning, in their user documents or product labels, for replacement fuses. Similar to: "replace only with same type and rating of fuse"; followed by a code: T1.6AH250V. And for those who may not understand the code, they may sometimes add in parentheses some variant of "(1.6 Amp time-lag, ~250V, high breaking capacity)".
So now to my question, US manufacturers sometimes use the phrase "SLO-BLO" or "Slow Blow" instead of Time-Lag or Time-Delay. Are these terms commonly used internationally and if so, are they clearly understood? I took some time to look up SLO-BLO and found it's a registered trademark for Littelfuse going back to 1957, and it has been continuously renewed since that time. Incidentally, a German Engineer once told me the way he would designate a fuse type for a variety of tripping characteristics was in this order from very slow to very fast: TT1.0A250V, T1.0A250V, 1.0A250V, F1.0A250V, FF1.0A250V.
