Hello,
I am repairing a circuitboard where there is a component marked "F" on the board which I beleve is a fuse. The text on the Component is "P030" and "250".

Is there anyone know anything about this? Want to be sure it is a fuse and do you know any replacement?

Thanks in advance,
Niklas

I can't tell if the symbol on the top of the device is a company logo or a voltage suppressor symbol (back to back diodes).
Can you get a better shot of the characters on the device?

It Looks like this.

AC ------[P030 250]--------[Transformatior]---------- AC

The other side is a bit complicated but haven't found an error there.
If that helps.
Isn't there any place to find thouse thing that is on the component?

If it's in series with the transformer primary as your sketch implies, it's a fuse, probably rated 250VAC 30mA. Why don't you test it with a meter? If it measures open, it's a blown fuse. If it measures short, it's a good fuse and if it measures a few Ohms, it's a PTC resettable thermal fuse.
