I^2t is simply current squared times the length of the surge. So if you want the fuse to blow if you have more than a 5A surge for 1/2 a sec, then the I^2t rating would be 12.5. Since the fuse has a resistance I^2R is the power dissipated and I^2Rt is the energy. The energy will determine the actual temperature rise. facts lebanon
