What happens if you put a smaller amp fuse?

Do not use a fuse with a lower rating– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.

Can I use a 2 amp fuse instead of a 2.5 amp?

As long as it is the same size, (physical) and the total amp draw is under 2, yes…

B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125\%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125\% = 100A. C Choose FUSE AMPERAGE near the middle of this range.

What is a 1 amp fuse used for?

1 AMP Ceramic Fuse are suitable for various different uses. These include providing reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.
