"Groovy" flat fuses VS non-groovy

[Eskimo007]

I recently needed to replace a 40amp DC flat fuse between my RV battery and inverter, and had the hardest time trying to insert the spare fuse that the original owner had provided. Upon (very) close inspection, I noticed that the replacement fuse although the exact same size and appearance as the burnt out one had some grooves on each side, whereas my replacement did not. Needless to say, trying to force the replacement in the holder brought no joy.


Does anyone know what the difference is between the 2 types? I'm thinking maybe slo-blow or not? Looking at the transparent casing of the fuses, I can see the inside is different.

It's a 40A like the Maxi. Will try to add a picture to my post that clearly shows the grooves above the blades on both sides.

Sounds like you’re talking about a blade type fuse, but you might want to clarify that before we get off too far in the weeds.

Is it one of these?

I think the only difference is the maker.. "Grooves" make it easier to grip with fingers.
I use tools to insert fuses. generally works

Compare the Tabs that come out of the fuse. I've seen some that I think are bigger.

Did you try turning the fuse around? But I don't know why a fuse would be directional.
