I had to scrounge some of this together from a Google search and a visit to the Wayback Machine, so here it is in one place:
Take, for example, "F800mAL250V"
F = "Fast Acting" (See below)
800mA = 800 milliamps (if you have to substitute, go lower)
L = General Application, Normal Blow. Protection of wiring
250V = 250 volts (if you have to substitute, I am pretty sure you want to go higher)
Electronic European Fuse Markings(Edit)
| FF or UR | Very Fast Acting, Semiconductor Protection Fuse |
| F | Fast Acting Fuse |
| M | Medium Acting Fuse |
| T or a Snail Shell | Slow Acting Fuse |
| TT | Very Slow Acting Fuse |
Industrial European Fuse Markings(Edit)
(gL, gG, gB, gTr, gR, aM, aR)
First letter(Edit)
g = Full Range, a = Partial Range
2nd Letter(Edit)
L = General Application, Normal Blow. Protection of wiring.
G = General Application, Normal Blow.
B = General Application, Normal Blow. Robust design for mining application.
Tr = Transformer Protection.
R = Very Fast Acting. Semiconductor Protection Fuse. What is the difference between aR and gR?
M = Protection of electrical motors. Capable of withstanding motor starts.
