I am trying to understand your mission on this forum.Maybe you should focus on that video too ... because the fuse did what it supposed to do.
Did not catch fire, no plasma explosion ... nothing.
It did work as it should.
No. It is a JLLN 200 Class T fuse and that has melamine body.
I more like the NT - NH fuses. Ceramic body, bigger, cheaper, better. But that Class T is fine too.
In that case the fuse is too weak, so the installer did not know what he is doing.
The fuse has an interrupt capacity. And it has to interrupt bellow that. Engineers designed and then quality control tested it.
Also it is always wise to oversize V and interrupt capacity ... only Amps stay.
Until you hit it with a hammer or drag it in the road ... that fuse will be fine.
And waaaay better than ANL or MEGA fuse in any fuseholder
The sand is inside the fuse body. Pressed. No need for any fuse holder for it to do its work.
Or maybe you do not want to hear any other arguments than yours.
What are you debating about?
Did the fuse work? Yes.
Without holder? Yes.
Better in a holder? Off course. But even without a holder light years better than anything most people use here.
a member asked what benefit or harm COULD happen without a holder… I gave a admittedly worst case scenario… one I have seen a great many times…
you come on and claim the holder’s one and only purpose is to mount the fuse.
Seriously… why are you arguing about these points?
Sure, the fuse in the video didn’t fail or melt down or anything of the sort… it was an EXTREMELY brief short. It could have been far worse.
