2Amp F2A F2AL 250v 10 Pieces Glass Fuse Fast Blow 20 x 5mm

When you drop an egg the chicken and the egg arrive at the impact point at close enough to the same time. If the fuse's resistance increases due to heat, and the load's resistance remains unchanged, the voltage across the fuse will also increase slightly, heating the fuse further and thus accelerating the blowing process.

I think that most people ignore the voltage because they assume that it remains fairly constant, which is true in the vast majority of the cases. If 6V DC was applied to this example fuse, 240 watts in this condition would be 40 A when the fuse would 'blow'. However you cannot use a low voltage fuse in high voltage applications : it will still blow at (strictly, slightly above) its rated current, but may sustain an arc that a HV fuse would extinguish.

Fuse Rating Inscription: is F2A 250v same With F2AL 250v? Fuse Rating Inscription: is F2A 250v same With F2AL 250v?

Over that and it will blow, the greater the overcurrent the quicker it blows, depending on slow- or quick-blow design, etc. If you don’t see what you are looking for just let us know and we will locate these fuses for you elsewhere. If you apply 240V to a circuit designed for 6V, the fuse will probably blow because the current in the circuit would be multiplied by 40 (240V/6V), thus the fuse would dissipate 40 It is the current that a fuse is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.
