PSW 505 Fuse: Fast or Slow Acting?

An incompetent electrician sent a surge through one panel of my house. Most important stuff was on surge protectors but not the sub. The fuse is not merely blown, it exploded. I can't tell if the replacement should be fast acting or delay acting, can someone advise?

    Thanks, I have that spec, but Amazon shows it as available in both fast and slow blow versions. Which should it be?

    Are you referring to Amazon having both fast and slow blow and you're still confused?

    Most fuses are made in both fast and slow blow. In your case you need fast blow. So that is what you need to replace it with.
