Max. continuous current at which the fuse will not trip at 25
º
C ambient.
Max. fault current the fuse can withstand at 25
º
C ambient without being damaged; fuse may withstand higher currents at lower voltages - test accordingly.
Min. current at which the fuse will trip at 25
º
C ambient, max. fuse temperature in tripped state is 125
º
C.
Power dissipated by the fuse when tripped at 25
