I need to replace a PSU fuse in an LCD monitor. The open fuse is
ceramic, 5 x 20 mm, and marked "T3.15AH250V", with no obvious spacing
between the various markings. I understand the speed rating (T) and the
voltage (250V), but I'm unclear on the amperage. Is it 3.15 amps, .15
amps, or 15 amps? Did some searching, but all I can find are pages
trying to sell fuses, not any giving how to read the ratings.

TIA

You mentioned that you have a number of different breakers fitted with clip leads for testing before you install an actual fuse. I hate to repeatedly blow fuses too, but doesn't that increase the time it takes for the circuit to open, thus subjecting the equipment to possible further harm? Lenny
