I'm looking for some fuseholders for 3AG type 1/4x1-1/4" fuses. They are standard fuse holders, but include an adapter that allows them to clip in to a standard 1/2" (nominal/trade size) conduit knockout (closer to 7/8" diameter).


does anyone know where I can buy these adapters, or where I can get fuse holders of similar size with this type of mount? The original is a Buss type HTA, which is now type HTB. None of the online catalogs show this adapter. Or maybe someone knows what I should search for? I looked and looked, but no luck at all.

The ones I've seen for box mounting are all HLR and HLQ style holders, with the captive fuses. I've never seen one for non-captive 3AG/AGC fuses.

6374 and 4909 are the adapter part numbers, and vary only in what panel thickness they mount onto.

Cooper Bussmann is the only maker, I believe.

Thanks. These were made by Bussman. The boxes these mount in unfortunately don't have the depth to accommodate those longer fuses. It almost looks like there should be a nut securing this holder to the knockout adapter, but they manage to just clip in there. I'll have to try a few more times to contact their customer service folks, and see if they can tell me anything.

Hi Jim,

I will look in to that. Also will search for "grommet" for some reason that word wasn't popping into my head when looking before, but the part I need is indeed a grommet. Thanks!

"Bushing" is another possible word to try. McMaster-Carr has a wide variety of types, not just the one I linked to.
