Fuse

I blew a fuse on my UPS. The fuse holder says the fuse is a T 5.0A fuse.
Wal-Mart didn't have any that were the same length as the one I had. We
couldn't even tell by the markings that Wal-Mart had on the fuses to be able
to tell what ratings they were.
I went to Radio Shack and they didn't have one but I did notice that they
cost almost 3 times as much as they did at Wal-Mart.
From the fuses I looked at Radio Shack it looks like the clear glass tube
fuses only have two types.
All the fuses that are slow blow are the same length but longer than the
instant trip kind which are all the same size but shorter.
Other than that you can put a 1 amp fuse or a 5 amp fuse in the same holder.
Right?

There are AGC (larger) and GMA (smaller) types. There are slow blo and regular versions. That determines how fast or how much overcurrent that fuse will withstand without blowing. Then there are low voltage (32 volt) and 250 volt versions. First learn the voltage and type (regular or slo blow) to obtain correct fuse of same physical size. Chances are the fuse must be a 250 volt type. If in doubt, get the 250 volt type. If fuse not available, then a temporary fuse of less amperes is quite acceptable. Chances are your UPS has internal problems; will be killing fuses anyway. Even a 2 amp fuse should work without failing if only for testing UPS integrity.

My UPS fuse blew when I plugged in another computer that had a bad power supply.
I am pretty sure I can select the right fuse when I find one.
One thing I wanted to mention again is that the fuses at Radio Shack where 3X as expensive as Wal-Mart but neither place had the fuse.
Are the 32V fuses fit in a 250V fuse holder? I bet those are the knife type.

Go to the parts drawers. Parts there sell for typically 5 and ten times. These are full retail prices. Walmart discounts.
Other well stocked sources for that fuse are Home Depot and Lowes.

You may need to go to a real electronics place or an electrical supply company. There are at least a dozen different types of fuse that is roughly the same size (nominally .25"dia 1.25 long). What is the type on the blown one? It should have the amps, volts and a 3 letter/number type ID. (3AB, ABC, AGC, MDL etc)

Did you ever think of contacting the original manufacture of your product?

Of course. I would like to try to find it locally first though. Thanks I know it is a UPS but it is not a very important UPS. :)
