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 amps) |
| L | General Application, Normal Blow. Protection of wiring |
| 250V | 250 volts (if you have to substitute, go higher volts) |
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)
| M | Protection of electrical motors. Capable of withstanding motor starts. |
| 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? |
