will a fuse rated at 2amps 125v protect a device rated at 2amps 6v? |

Yes. The current is what trips the fuse. Under normal operation, a fuse has almost zero voltage across it because its resistance is very low. See also: https://ultimateelectronicsbook.com/resistor-power-rating/ The maximum voltage rating on a fuse tells you about what happens when the fuse blows, at which point you have zero current but potentially a high voltage across the fuse terminals. You don't want arcing across a blown fuse, for example. |
