They were fuses, not breakers. Plug fuses to be exact.

That sounds a bit like an open neutral problem. Though without more
information, it could also be loose lugs, or a bad splice.

You may have one after that - A short like that can burn a hole in a
pipe. But you have to understand that there is a big difference
between a fuse and a breaker. When a fuse blows, you have to replace
it. (Or replace the link in renewable link fuse.) When a breaker
trips, you can reset it - usually by moving the the handle to off,
and then on. There are advantages and disadvantages of both.
