The GMA series of fuse is a fast acting glass tube fuse. The dimensions are 5 X 20 mm. This series of fuse's amperage span is from 63 mA right up to 8 amps. I would suggest that your fuse is rated at 250 mA or (1/4 of an amp) with a 250 volt rating.
The amperage of a T2L 250v fuse is typically 8 amps. It is a misconception that it has an amperage of 3.
The current rating is 2A (2 amps).
It is ok to use a fuse with a higher amperage rating and not ok to use a fuse with a smaller amperage rating why?
No, the voltage rating should not be exceeded. However, you could use a 250v 10a fuse for a 125v 10a fuse.
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.
Yes, a 250V fuse can replace a 125V fuse if they have the same ampacity rating. The voltage rating is simply the maximum voltage that the fuse is capable of safely interrupting. You can go higher, but you can not go lower. Obviously, the form factor of the fuse must be the same, but that is often the case.
yes. the 250v just means that's the maximum voltage rating the fuse can handle .. so it can def handle 125v. just not vice versa.
No
nope
The function of a fuse is to stop the current from flowing by opening the circuit when the circuit amperage exceeds the rating of the fuse.
I have a T10L 250V fuse in a control system and don not know what amperage this is. Can someone help ?? You can replace a 400ma fuse with a smaller amp fuse but never with a larger amp fuse. The amperage of the fuse is written on the fuse somewhere. If it has a 125 volt fuse then replace it with a 125 volt fuse. I got that, thanks!! The problem is that there is no amperage indicated on the fuse, only the T10L, and I was wondering if this is just the type of fuse, or if it was a codification of the amperage, like a 10A delayed or something... Class T fuses are non-renewable, current-limiting, and conform to UL 198H. Current ratings range from 0A to 1200A for 300V rated fuses, and 0A to 1,200A for 600VAC rated fuses (DC ratings are also available). The interrupting rating is 200kA rms symmetrical and these fuses are designed for protection of feeders and branch circuits in accordance with the NEC. Class T fuses must be labeled "Current Limiting", and may be labeled "Time Delay" if they pass time-delay requirements. I can find no listing for a T10L fuse in this class, so I cannot find the amp rating on this fuse. My guess is that it is a 10 amp fuse, which is far greater than a 400 ma fuse. So my answer is no, you cannot use this fuse.
It may or may not. And because you are going to a smaller fuse than before, it is safe to try it.
