Can a fuse prevent electrical fires? How?

[Anonymous user]

Hello,

I’d like to know if a fuse can prevent electrical fires into a cabinet.

If yes, how does it works?

Thanks for your feedbacks.

Hey @Teflot,

On its own fuses do not prevent electrical fires.
An fuse stops delivering current when it breaks / melts due to overcurrent (too much)

This overflow can ofcourse be generated by something broken that can cause an fire, but that could (in some cases) already happen before the fuse cuts out.

Here are some explanations how a fuse works and what it does;

And even an nice animated video here, (first part is about the fuse);

EDIT:
An component that can help prevent electrical fires can be found here on this forum;

Hope this is of any help!
