Mike,
Fuse-holders shall be marked with the symbol relative to the time/current
characteristic (F or T), the rated current (mA or A), and the rated voltage
(V) of the fuse.
Examples: F250mA 250V (fast acting)
T3A 250V ("slow blow")

I am in the process of updating markings for power ratings on a product
that
needs a marking for a FAST blow fuse. Is there a reference out there that
shows the letter designations for the various blow open speeds? I looked in
the IEC 417 and in UL1950 3rd edition to no avail. The search goes on.
