Since I do not have a lot of equipment right now, I am trying to find an alternative to strip a plug fuse using fire or heat. I tried to put it on heat for about 2 minutes, but when I tried it again, it is still working. Is this even possible?

  • \$\begingroup\$ Approximately, what would be the temperature to melt it? I believe I got it for about 80 degree Celsius. \$\endgroup\$

    \$\begingroup\$ I expect the melting point is well above 100 C, but I try not ot melt fuses, so don't know. \$\endgroup\$ Commented Nov 27, 2020 at 4:32

    \$\begingroup\$ why are you doing this? ... it makes me think that your end goal is something different \$\endgroup\$

I think you need more than 80C. Need more info about the fuse and material of the fuse strip.

    \$\begingroup\$ Wow. It really wouldn't easy to melt it by heat then. \$\endgroup\$

    \$\begingroup\$ If a large amount of current went thorugh it (as it is slightly resistive, then it would be quite easy to melt. But you know that, because that's what it is designed to do. :) \$\endgroup\$

    \$\begingroup\$ It may be easy to short circuit using 12V high discharge rate battery (Lead Acid Car battery or LiPo) without any over current protection circuit (direct connection short circuit through fuse) to blow your fuse and try to obtain the temperature from that way. But if your fuse amp rating is way higher than normal 5,15,20A fuse, you may need bigger power source. \$\endgroup\$ Commented Nov 27, 2020 at 5:08
  • \$\begingroup\$ Yep, you are right. It is easier to use electricity to melt this in nanosecond, I did the old school short circuiting it using fork and 220 voltage. No it isn't working anymore \$\endgroup\$
