About Fuse

What is the rating of conventional rewirable fuse, MCB etc.

What is the rating of polyfuse(resettable fuse or PPTC fuse). Polyfuse are normally used in electronic circuits.

Can we replace conventional household power supply main rewirable fuse with these polyfuse. Is it available in such high power requirement?

Pls help.😔

i think rewirable fuse is more better because if any fault occur normal people also can repair it

Polyfuse doesn't need any repair. It will automatically get reset when fault disappears from the circuit.

But my doubt is, they are small fuses used in electronic circuits. Can we replace main fuse in our house hold (fuse near to energy meter) with this polyfuse? Is polyfuse available for this higher rating?

#-Link-Snipped-#'m talking about this fuse.

Can we replace main fuse(rewirable fuse/mcb) we use near energy meter in our household by this polyfuse? If not, then why?
